# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at dev@caxy.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]
[homepage]: http://contributor-covenant.org
[version]: http://contributor-covenant.org/version/1/4/

Contributing
============
First of all, **thank you** for contributing, **you are awesome**!
Here are a few rules to follow in order to ease code reviews, and discussions before
maintainers accept and merge your work.
You MUST follow the [PSR-1](http://www.php-fig.org/psr/1/) and
[PSR-2](http://www.php-fig.org/psr/2/). If you don't know about any of them, you
should really read the recommendations. Can't wait? Use the [PHP-CS-Fixer
tool](http://cs.sensiolabs.org/).
You MUST run the test suite.
You MUST write (or update) unit tests.
You SHOULD write documentation.
Please, write [commit messages that make
sense](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html),
and [rebase your branch](http://git-scm.com/book/en/Git-Branching-Rebasing)
before submitting your Pull Request.
One may ask you to [squash your
commits](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html)
too. This is used to "clean" your Pull Request before merging it (we don't want
commits such as `fix tests`, `fix 2`, `fix 3`, etc.).
Also, while creating your Pull Request on GitHub, you MUST write a description
which gives the context and/or explains why you are creating it.
Thank you!

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does.
Copyright (C) yyyy name of author
This program is free software; you can redistribute it and/or
modify it under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2
of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'. This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'
(which makes passes at compilers) written
by James Hacker.
signature of Ty Coon, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

php-htmldiff is a library for comparing two HTML files/snippets and highlighting the differences using simple HTML.
This HTML Diff implementation was forked from [rashid2538/php-htmldiff][upstream] and has been modified with new features,
bug fixes, and enhancements to the original code.
For more information on these modifications, read the [differences from rashid2538/php-htmldiff][differences] or view the [CHANGELOG][changelog].
## Installation
The recommended way to install php-htmldiff is through [Composer][composer].
Require the [caxy/php-htmldiff][badge_packagist] package by running following command:
```sh
composer require caxy/php-htmldiff
```
This will resolve the latest stable version.
Otherwise, install the library and setup the autoloader yourself.
### Working with Symfony
If you are using Symfony, you can use the [caxy/HtmlDiffBundle][htmldiffbundle] to make life easy!
## Usage
```php
use Caxy\HtmlDiff\HtmlDiff;
$htmlDiff = new HtmlDiff($oldHtml, $newHtml);
$content = $htmlDiff->build();
```
## Configuration
The configuration for HtmlDiff is contained in the `Caxy\HtmlDiff\HtmlDiffConfig` class.
There are two ways to set the configuration:
1. [Configure an Existing HtmlDiff Object](#configure-an-existing-htmldiff-object)
2. [Create and Use a HtmlDiffConfig Object](#create-and-use-a-htmldiffconfig-object)
#### Configure an Existing HtmlDiff Object
When a new `HtmlDiff` object is created, it creates a `HtmlDiffConfig` object with the default configuration.
You can change the configuration using setters on the object:
```php
use Caxy\HtmlDiff\HtmlDiff;
// ...
$htmlDiff = new HtmlDiff($oldHtml, $newHtml);
// Set some of the configuration options.
$htmlDiff->getConfig()
->setMatchThreshold(80)
->setInsertSpaceInReplace(true)
;
// Calculate the differences using the configuration and get the html diff.
$content = $htmlDiff->build();
// ...
```
#### Create and Use a HtmlDiffConfig Object
You can also set the configuration by creating an instance of
`Caxy\HtmlDiff\HtmlDiffConfig` and using it when creating a new `HtmlDiff`
object using `HtmlDiff::create`.
This is useful when creating more than one instance of `HtmlDiff`:
```php
use Caxy\HtmlDiff\HtmlDiff;
use Caxy\HtmlDiff\HtmlDiffConfig;
// ...
$config = new HtmlDiffConfig();
$config
->setMatchThreshold(95)
->setInsertSpaceInReplace(true)
;
// Create an HtmlDiff object with the custom configuration.
$firstHtmlDiff = HtmlDiff::create($oldHtml, $newHtml, $config);
$firstContent = $firstHtmlDiff->build();
$secondHtmlDiff = HtmlDiff::create($oldHtml2, $newHtml2, $config);
$secondHtmlDiff->getConfig()->setMatchThreshold(50);
$secondContent = $secondHtmlDiff->build();
// ...
```
#### Full Configuration with Defaults:
```php
$config = new HtmlDiffConfig();
$config
// Percentage required for list items to be considered a match.
->setMatchThreshold(80)
// Set the encoding of the text to be diffed.
->setEncoding('UTF-8')
// If true, a space will be added between the <del> and <ins> tags of text that was replaced.
->setInsertSpaceInReplace(false)
// Option to disable the new Table Diffing feature and treat tables as regular text.
->setUseTableDiffing(true)
// Pass an instance of \Doctrine\Common\Cache\Cache to cache the calculated diffs.
->setCacheProvider(null)
// Set the cache directory that HTMLPurifier should use.
->setPurifierCacheLocation(null)
// Group consecutive deletions and insertions instead of showing a deletion and insertion for each word individually.
->setGroupDiffs(true)
// List of characters to consider part of a single word when in the middle of text.
->setSpecialCaseChars(array('.', ',', '(', ')', '\''))
// List of tags to treat as special case tags.
->setSpecialCaseTags(array('strong', 'b', 'i', 'big', 'small', 'u', 'sub', 'sup', 'strike', 's', 'p'))
// List of tags (and their replacement strings) to be diffed in isolation.
->setIsolatedDiffTags(array(
'ol' => '[[REPLACE_ORDERED_LIST]]',
'ul' => '[[REPLACE_UNORDERED_LIST]]',
'sub' => '[[REPLACE_SUB_SCRIPT]]',
'sup' => '[[REPLACE_SUPER_SCRIPT]]',
'dl' => '[[REPLACE_DEFINITION_LIST]]',
'table' => '[[REPLACE_TABLE]]',
'strong' => '[[REPLACE_STRONG]]',
'b' => '[[REPLACE_B]]',
'em' => '[[REPLACE_EM]]',
'i' => '[[REPLACE_I]]',
'a' => '[[REPLACE_A]]',
))
;
```

Differences from rashid2538/php-htmldiff
========================================
.. contents:: Table of Contents
Code Styling and Clean-up
-------------------------
* Added namespaces, split up classes to their own files, some code styling changes
Enhancements
------------
* Allow the specialCaseOpeningTags and specialCaseClosingTags properties to be modified by passing an array into the constructor or using set/add/remove functions
* Updated the demo to accept input and diff via AJAX
* Added static properties for the default config variables
Bug Fixes
---------
* Fixed an index out of range bug (may have been fixed on the original repo since): c9ba1fa_
* Check for empty oldText or newText before processing del or ins in processReplaceOperation function
New Features
------------
Isolated Diffing of certain HTML elements
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is the one of the largest changes from the original repository.
For more information, see the release notes for tag `0.0.6`_
List Diffing
^^^^^^^^^^^^
Similar to the Isolated Diffing feature, but specifically for HTML lists.
More information is to come on this, and there will definitely be some tweaks and configuration options added for this
feature. Currently there is no easy way to enable/disable the feature, so if you're having issues with it I suggest
using the `0.0.6`_ or earlier release.
Table Diffing
^^^^^^^^^^^^^
Similar to the Isolated Diffing and List Diffing features, but specifically for HTML tables.
More information to come on this soon.
New option to group together diffed words by not matching on whitespace-only. Option is enabled by default.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This was a specific requirement for an application we use this library for. The original library would replace
single words at a time, but enabling this feature will group replacements instead. See example below.
Old Text::
testing some text here and there
New Text::
testing other words here and there
With $groupDiffs = false (original functionality)::
testing <del>some</del><ins>other</ins> <del>text</del><ins>words</ins> here and there
With $groupDiffs = true (new feature)::
testing <del>some text</del><ins>other words</ins> here and there
Change diffing to strike through entire words/numbers if they contain periods or commas within the word
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This change introduced a new property ``$specialCaseChars``, which defaults to the following characters: ``.`` ``,`` ``(`` ``)`` ``'``
This feature can be "disabled" by simply setting the $specialCaseChars to an empty array i.e. ``$diff->setSpecialCaseChars(array())``
In the original library, special characters are treated as their own "words" even if they are in the middle of a word.
This causes weird things to happen when diffing numbers that have a comma or a period in the middle of the number.
For example, diffing ``10,000.50`` against ``11,100.75`` gives you:
Original Functionality::
<del class="diffmod">10</del><ins class="diffmod">11</ins>,<del class="diffmod">000</del><ins class="diffmod">100</ins>.<del class="diffmod">50</del><ins class="diffmod">75</ins>
This is very difficult to read, so the new feature allows you to add ``.`` and ``,`` to the ``$specialCaseChars`` array in order
to get output that looks like::
<del class="diffmod">10,000.50</del><ins class="diffmod">11,100.75</ins>
Note: It will *not* treat the specialCaseChars as part of the word if it is at the beginning or end of the word,
so normal periods or commas at the end of words will still be diffed like the original.
Added option to insert a space between ``<del>`` and ``<ins>`` tags. Disabled by default.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This was a requirement for one our applications that uses this library.
New property ``$insertSpaceInReplace`` was added, and setting it to true will simply add a space between
the ``<del>`` and ``<ins>`` tags in replace operations, which was requested for easier reading.
Enable it by calling ``$diff->setInsertSpaceInReplace(true);``
Original Functionality::
<del>Old</del><ins>New</ins>
New Functionality::
<del>Old</del> <ins>New</ins>

How to install HTML Purifier
HTML Purifier is designed to run out of the box, so actually using the
library is extremely easy. (Although... if you were looking for a
step-by-step installation GUI, you've downloaded the wrong software!)
While the impatient can get going immediately with some of the sample
code at the bottom of this library, it's well worth reading this entire
document--most of the other documentation assumes that you are familiar
with these contents.
---------------------------------------------------------------------------
1. Compatibility
HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and
up. It has no core dependencies with other libraries. PHP
4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0.
HTML Purifier is not compatible with zend.ze1_compatibility_mode.
These optional extensions can enhance the capabilities of HTML Purifier:
* iconv : Converts text to and from non-UTF-8 encodings
* bcmath : Used for unit conversion and imagecrash protection
* tidy : Used for pretty-printing HTML
These optional libraries can enhance the capabilities of HTML Purifier:
* CSSTidy : Clean CSS stylesheets using %Core.ExtractStyleBlocks
* Net_IDNA2 (PEAR) : IRI support using %Core.EnableIDNA
---------------------------------------------------------------------------
2. Reconnaissance
A big plus of HTML Purifier is its inerrant support of standards, so
your web-pages should be standards-compliant. (They should also use
semantic markup, but that's another issue altogether, one HTML Purifier
cannot fix without reading your mind.)
HTML Purifier can process these doctypes:
* XHTML 1.0 Transitional (default)
* XHTML 1.0 Strict
* HTML 4.01 Transitional
* HTML 4.01 Strict
* XHTML 1.1
...and these character encodings:
* UTF-8 (default)
* Any encoding iconv supports (with crippled internationalization support)
These defaults reflect what my choices would be if I were authoring an
HTML document, however, what you choose depends on the nature of your
codebase. If you don't know what doctype you are using, you can determine
the doctype from this identifier at the top of your source code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...and the character encoding from this code:
<meta http-equiv="Content-type" content="text/html;charset=ENCODING">
If the character encoding declaration is missing, STOP NOW, and
read 'docs/enduser-utf8.html' (web accessible at
http://htmlpurifier.org/docs/enduser-utf8.html). In fact, even if it is
present, read this document anyway, as many websites specify their
document's character encoding incorrectly.
---------------------------------------------------------------------------
3. Including the library
The procedure is quite simple:
require_once '/path/to/library/HTMLPurifier.auto.php';
This will setup an autoloader, so the library's files are only included
when you use them.
Only the contents in the library/ folder are necessary, so you can remove
everything else when using HTML Purifier in a production environment.
If you installed HTML Purifier via PEAR, all you need to do is:
require_once 'HTMLPurifier.auto.php';
Please note that the usual PEAR practice of including just the classes you
want will not work with HTML Purifier's autoloading scheme.
Advanced users, read on; other users can skip to section 4.
Autoload compatibility
----------------------
HTML Purifier attempts to be as smart as possible when registering an
autoloader, but there are some cases where you will need to change
your own code to accomodate HTML Purifier. These are those cases:
PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
Because spl_autoload_register() doesn't exist in early versions
of PHP 5, HTML Purifier has no way of adding itself to the autoload
stack. Modify your __autoload function to test
HTMLPurifier_Bootstrap::autoload($class)
For example, suppose your autoload function looks like this:
function __autoload($class) {
require str_replace('_', '/', $class) . '.php';
return true;
}
A modified version with HTML Purifier would look like this:
function __autoload($class) {
if (HTMLPurifier_Bootstrap::autoload($class)) return true;
require str_replace('_', '/', $class) . '.php';
return true;
}
Note that there *is* some custom behavior in our autoloader; the
original autoloader in our example would work for 99% of the time,
but would fail when including language files.
AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
spl_autoload_register() has the curious behavior of disabling
the existing __autoload() handler. Users need to explicitly
spl_autoload_register('__autoload'). Because we use SPL when it
is available, __autoload() will ALWAYS be disabled. If __autoload()
is declared before HTML Purifier is loaded, this is not a problem:
HTML Purifier will register the function for you. But if it is
declared afterwards, it will mysteriously not work. This
snippet of code (after your autoloader is defined) will fix it:
spl_autoload_register('__autoload')
Users should also be on guard if they use a version of PHP previous
to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
for you, which can collide with an autoloader that was added by *you*
later.
For better performance
----------------------
Opcode caches, which greatly speed up PHP initialization for scripts
with large amounts of code (HTML Purifier included), don't like
autoloaders. We offer an include file that includes all of HTML Purifier's
files in one go in an opcode cache friendly manner:
// If /path/to/library isn't already in your include path, uncomment
// the below line:
// require '/path/to/library/HTMLPurifier.path.php';
require 'HTMLPurifier.includes.php';
Optional components still need to be included--you'll know if you try to
use a feature and you get a class doesn't exists error! The autoloader
can be used in conjunction with this approach to catch classes that are
missing. Simply add this afterwards:
require 'HTMLPurifier.autoload.php';
Standalone version
------------------
HTML Purifier has a standalone distribution; you can also generate
a standalone file from the full version by running the script
maintenance/generate-standalone.php . The standalone version has the
benefit of having most of its code in one file, so parsing is much
faster and the library is easier to manage.
If HTMLPurifier.standalone.php exists in the library directory, you
can use it like this:
require '/path/to/HTMLPurifier.standalone.php';
This is equivalent to including HTMLPurifier.includes.php, except that
the contents of standalone/ will be added to your path. To override this
behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
be found (usually, this will be one directory up, the "true" library
directory in full distributions). Don't forget to set your path too!
The autoloader can be added to the end to ensure the classes are
loaded when necessary; otherwise you can manually include them.
To use the autoloader, use this:
require 'HTMLPurifier.autoload.php';
For advanced users
------------------
HTMLPurifier.auto.php performs a number of operations that can be done
individually. These are:
HTMLPurifier.path.php
Puts /path/to/library in the include path. For high performance,
this should be done in php.ini.
HTMLPurifier.autoload.php
Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
You can do these operations by yourself--in fact, you must modify your own
autoload handler if you are using a version of PHP earlier than PHP 5.1.2
(See "Autoload compatibility" above).
---------------------------------------------------------------------------
4. Configuration
HTML Purifier is designed to run out-of-the-box, but occasionally HTML
Purifier needs to be told what to do. If you answer no to any of these
questions, read on; otherwise, you can skip to the next section (or, if you're
into configuring things just for the heck of it, skip to 4.3).
* Am I using UTF-8?
* Am I using XHTML 1.0 Transitional?
If you answered no to any of these questions, instantiate a configuration
object and read on:
$config = HTMLPurifier_Config::createDefault();
4.1. Setting a different character encoding
You really shouldn't use any other encoding except UTF-8, especially if you
plan to support multilingual websites (read section three for more details).
However, switching to UTF-8 is not always immediately feasible, so we can
adapt.
HTML Purifier uses iconv to support other character encodings, as such,
any encoding that iconv supports <http://www.gnu.org/software/libiconv/>
HTML Purifier supports with this code:
$config->set('Core.Encoding', /* put your encoding here */);
An example usage for Latin-1 websites (the most common encoding for English
websites):
$config->set('Core.Encoding', 'ISO-8859-1');
Note that HTML Purifier's support for non-Unicode encodings is crippled by the
fact that any character not supported by that encoding will be silently
dropped, EVEN if it is ampersand escaped. If you want to work around
this, you are welcome to read docs/enduser-utf8.html for a fix,
but please be cognizant of the issues the "solution" creates (for this
reason, I do not include the solution in this document).
4.2. Setting a different doctype
For those of you using HTML 4.01 Transitional, you can disable
XHTML output like this:
$config->set('HTML.Doctype', 'HTML 4.01 Transitional');
Other supported doctypes include:
* HTML 4.01 Strict
* HTML 4.01 Transitional
* XHTML 1.0 Strict
* XHTML 1.0 Transitional
* XHTML 1.1
4.3. Other settings
There are more configuration directives which can be read about
here: <http://htmlpurifier.org/live/configdoc/plain.html> They're a bit boring,
but they can help out for those of you who like to exert maximum control over
your code. Some of the more interesting ones are configurable at the
demo <http://htmlpurifier.org/demo.php> and are well worth looking into
for your own system.
For example, you can fine tune allowed elements and attributes, convert
relative URLs to absolute ones, and even autoparagraph input text! These
are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
translates to:
$config->set('Namespace.Directive', $value);
E.g.
$config->set('HTML.Allowed', 'p,b,a[href],i');
$config->set('URI.Base', 'http://www.example.com');
$config->set('URI.MakeAbsolute', true);
$config->set('AutoFormat.AutoParagraph', true);
---------------------------------------------------------------------------
5. Caching
HTML Purifier generates some cache files (generally one or two) to speed up
its execution. For maximum performance, make sure that
library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
If you are in the library/ folder of HTML Purifier, you can set the
appropriate permissions using:
chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
If the above command doesn't work, you may need to assign write permissions
to all. This may be necessary if your webserver runs as nobody, but is
not recommended since it means any other user can write files in the
directory. Use:
chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
You can also chmod files via your FTP client; this option
is usually accessible by right clicking the corresponding directory and
then selecting "chmod" or "file permissions".
Starting with 2.0.1, HTML Purifier will generate friendly error messages
that will tell you exactly what you have to chmod the directory to, if in doubt,
follow its advice.
If you are unable or unwilling to give write permissions to the cache
directory, you can either disable the cache (and suffer a performance
hit):
$config->set('Core.DefinitionCache', null);
Or move the cache directory somewhere else (no trailing slash):
$config->set('Cache.SerializerPath', '/home/user/absolute/path');
---------------------------------------------------------------------------
6. Using the code
The interface is mind-numbingly simple:
$purifier = new HTMLPurifier($config);
$clean_html = $purifier->purify( $dirty_html );
That's it! For more examples, check out docs/examples/ (they aren't very
different though). Also, docs/enduser-slow.html gives advice on what to
do if HTML Purifier is slowing down your application.
---------------------------------------------------------------------------
7. Quick install
First, make sure library/HTMLPurifier/DefinitionCache/Serializer is
writable by the webserver (see Section 5: Caching above for details).
If your website is in UTF-8 and XHTML Transitional, use this code:
<?php
require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);
$clean_html = $purifier->purify($dirty_html);
?>
If your website is in a different encoding or doctype, use this code:
<?php
require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
$config = HTMLPurifier_Config::createDefault();
$config->set('Core.Encoding', 'ISO-8859-1'); // replace with your encoding
$config->set('HTML.Doctype', 'HTML 4.01 Transitional'); // replace with your doctype
$purifier = new HTMLPurifier($config);
$clean_html = $purifier->purify($dirty_html);
?>

Installation
Comment installer HTML Purifier
Attention : Ce document est encodé en UTF-8, si les lettres avec des accents
ne s'affichent pas, prenez un meilleur éditeur de texte.
L'installation de HTML Purifier est très simple, parce qu'il n'a pas besoin
de configuration. Pour les utilisateurs impatients, le code se trouve dans le
pied de page, mais je recommande de lire le document.
1. Compatibilité
HTML Purifier fonctionne avec PHP 5. PHP 5.0.5 est la dernière version testée.
Il ne dépend pas d'autres librairies.
Les extensions optionnelles sont iconv (généralement déjà installée) et tidy
(répendue aussi). Si vous utilisez UTF-8 et que vous ne voulez pas l'indentation,
vous pouvez utiliser HTML Purifier sans ces extensions.
2. Inclure la librairie
Quand vous devez l'utilisez, incluez le :
require_once('/path/to/library/HTMLPurifier.auto.php');
Ne pas l'inclure si ce n'est pas nécessaire, car HTML Purifier est lourd.
HTML Purifier utilise "autoload". Si vous avez défini la fonction __autoload,
vous devez ajouter cette fonction :
spl_autoload_register('__autoload')
Plus d'informations dans le document "INSTALL".
3. Installation rapide
Si votre site Web est en UTF-8 et XHTML Transitional, utilisez :
<?php
require_once('/path/to/htmlpurifier/library/HTMLPurifier.auto.php');
$purificateur = new HTMLPurifier();
$html_propre = $purificateur->purify($html_a_purifier);
?>
Sinon, utilisez :
<?php
require_once('/path/to/html/purifier/library/HTMLPurifier.auto.load');
$config = $HTMLPurifier_Config::createDefault();
$config->set('Core', 'Encoding', 'ISO-8859-1'); //Remplacez par votre
encodage
$config->set('Core', 'XHTML', true); //Remplacer par false si HTML 4.01
$purificateur = new HTMLPurifier($config);
$html_propre = $purificateur->purify($html_a_purifier);
?>

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!

All about HTML Purifier
HTML Purifier is an HTML filtering solution that uses a unique combination
of robust whitelists and agressive parsing to ensure that not only are
XSS attacks thwarted, but the resulting HTML is standards compliant.
HTML Purifier is oriented towards richly formatted documents from
untrusted sources that require CSS and a full tag-set. This library can
be configured to accept a more restrictive set of tags, but it won't be
as efficient as more bare-bones parsers. It will, however, do the job
right, which may be more important.
Places to go:
* See INSTALL for a quick installation guide
* See docs/ for developer-oriented documentation, code examples and
an in-depth installation guide.
* See WYSIWYG for information on editors like TinyMCE and FCKeditor
HTML Purifier can be found on the web at: http://htmlpurifier.org/

TODO List
= KEY ====================
# Flagship
- Regular
? Maybe I'll Do It
==========================
If no interest is expressed for a feature that may require a considerable
amount of effort to implement, it may get endlessly delayed. Do not be
afraid to cast your vote for the next feature to be implemented!
Things to do as soon as possible:
- http://htmlpurifier.org/phorum/read.php?3,5560,6307#msg-6307
- Think about allowing explicit order of operations hooks for transforms
- Fix "<.<" bug (trailing < is removed if not EOD)
- Build in better internal state dumps and debugging tools for remote
debugging
- Allowed/Allowed* have strange interactions when both set
? Transform lone embeds into object tags
- Deprecated config options that emit warnings when you set them (with'
a way of muting the warning if you really want to)
- Make HTML.Trusted work with Output.FlashCompat
- HTML.Trusted and HTML.SafeObject have funny interaction; general
problem is what to do when a module "supersedes" another
(see also tables and basic tables.) This is a little dicier
because HTML.SafeObject has some extra functionality that
trusted might find useful. See http://htmlpurifier.org/phorum/read.php?3,5762,6100
FUTURE VERSIONS
---------------
4.8 release [OMG CONFIG PONIES]
! Fix Printer. It's from the old days when we didn't have decent XML classes
! Factor demo.php into a set of Printer classes, and then create a stub
file for users here (inside the actual HTML Purifier library)
- Fix error handling with form construction
- Do encoding validation in Printers, or at least, where user data comes in
- Config: Add examples to everything (make built-in which also automatically
gives output)
- Add "register" field to config schemas to eliminate dependence on
naming conventions (try to remember why we ultimately decided on tihs)
5.0 release [HTML 5]
# Swap out code to use html5lib tokenizer and tree-builder
! Allow turning off of FixNesting and required attribute insertion
5.1 release [It's All About Trust] (floating)
# Implement untrusted, dangerous elements/attributes
# Implement IDREF support (harder than it seems, since you cannot have
IDREFs to non-existent IDs)
- Implement <area> (client and server side image maps are blocking
on IDREF support)
# Frameset XHTML 1.0 and HTML 4.01 doctypes
- Figure out how to simultaneously set %CSS.Trusted and %HTML.Trusted (?)
5.2 release [Error'ed]
# Error logging for filtering/cleanup procedures
# Additional support for poorly written HTML
- Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
- Friendly strict handling of <address> (block -> <br>)
- XSS-attempt detection--certain errors are flagged XSS-like
- Append something to duplicate IDs so they're still usable (impl. note: the
dupe detector would also need to detect the suffix as well)
6.0 release [Beyond HTML]
# Legit token based CSS parsing (will require revamping almost every
AttrDef class). Probably will use CSSTidy
# More control over allowed CSS properties using a modularization
# IRI support (this includes IDN)
- Standardize token armor for all areas of processing
7.0 release [To XML and Beyond]
- Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
- Hooks for adding custom processors to custom namespaced tags and
attributes, offer default implementation
- Lots of documentation and samples
Ongoing
- More refactoring to take advantage of PHP5's facilities
- Refactor unit tests into lots of test methods
- Plugins for major CMSes (COMPLEX)
- phpBB
- Also, a FAQ for extension writers with HTML Purifier
AutoFormat
- Smileys
- Syntax highlighting (with GeSHi) with <pre> and possibly <?php
- Look at http://drupal.org/project/Modules/category/63 for ideas
Neat feature related
! Support exporting configuration, so users can easily tweak settings
in the demo, and then copy-paste into their own setup
- Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
- Allow scoped="scoped" attribute in <style> tags; may be troublesome
because regular CSS has no way of uniquely identifying nodes, so we'd
have to generate IDs
- Explain how to use HTML Purifier in non-PHP languages / create
a simple command line stub (or complicated?)
- Fixes for Firefox's inability to handle COL alignment props (Bug 915)
- Automatically add non-breaking spaces to empty table cells when
empty-cells:show is applied to have compatibility with Internet Explorer
- Table of Contents generation (XHTML Compiler might be reusable). May also
be out-of-band information.
- Full set of color keywords. Also, a way to add onto them without
finalizing the configuration object.
- Write a var_export and memcached DefinitionCache - Denis
- Built-in support for target="_blank" on all external links
- Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
Also, enable disabling of directionality
? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
? Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
1. Analyzing which tags to remove duplicants
2. Ensure attributes are merged into the parent tag
3. Extend the tag exclusion system to specify whether or not the
contents should be dropped or not (currently, there's code that could do
something like this if it didn't drop the inner text too.)
? Make AutoParagraph also support paragraph-izing double <br> tags, and not
just double newlines. This is kind of tough to do in the current framework,
though, and might be reasonably approximated by search replacing double <br>s
with newlines before running it through HTML Purifier.
Maintenance related (slightly boring)
# CHMOD install script for PEAR installs
! Factor out command line parser into its own class, and unit test it
- Reduce size of internal data-structures (esp. HTMLDefinition)
- Allow merging configurations. Thus,
a -> b -> default
c -> d -> default
becomes
a -> b -> c -> d -> default
Maybe allow more fine-grained tuning of this behavior. Alternatively,
encourage people to use short plist depths before building them up.
- Time PHPT tests
ChildDef related (very boring)
- Abstract ChildDef_BlockQuote to work with all elements that only
allow blocks in them, required or optional
- Implement lenient <ruby> child validation
Wontfix
- Non-lossy smart alternate character encoding transformations (unless
patch provided)
- Pretty-printing HTML: users can use Tidy on the output on entire page
- Native content compression, whitespace stripping: use gzip if this is
really important

WYSIWYG - What You See Is What You Get
HTML Purifier: A Pretty Good Fit for TinyMCE and FCKeditor
Javascript-based WYSIWYG editors, simply stated, are quite amazing. But I've
always been wary about using them due to security issues: they handle the
client-side magic, but once you've been served a piping hot load of unfiltered
HTML, what should be done then? In some situations, you can serve it uncleaned,
since you only offer these facilities to trusted(?) authors.
Unfortunantely, for blog comments and anonymous input, BBCode, Textile and
other markup languages still reign supreme. Put simply: filtering HTML is
hard work, and these WYSIWYG authors don't offer anything to alleviate that
trouble. Therein lies the solution:
HTML Purifier is perfect for filtering pure-HTML input from WYSIWYG editors.
Enough said.
