I know this topic is really old, but since it's still relevant, I decided to respond. Especially when the landscape has changed since the question was originally asked.

You can use <a href="https://github.com/xemlock/htmlpurifier-html5" rel="nofollow noreferrer">https://github.com/xemlock/htmlpurifier-html5</a> which extends HTML Purifier with spec compliant definitions of HTML5 elements and attributes.

The usage is almost the same as the original HTML Purifier, you just need to replace <code>HTMLPurifier_Config</code> with <code>HTMLPurifier_HTML5Config</code>:

<pre><code>$config = HTMLPurifier_HTML5Config::createDefault();
$purifier = new HTMLPurifier($config);

$clean_html5 = $purifier-&gt;purify($dirty_html5);
</code></pre>

Disclaimer: I'm the author of the extension.

Is there a simple approach to add a HTML5 ruleset for HTMLPurifier?

HP can be <a href="http://htmlpurifier.org/docs/enduser-customize.html" rel="nofollow noreferrer">configured to</a> recognize new tags with:

<pre><code>// setup configurable HP instance
$config = HTMLPurifier_Config::createDefault();
$config-&gt;set('HTML.DefinitionID', 'html5 draft');
$config-&gt;set('HTML.DefinitionRev', 1);
$config-&gt;set('Cache.DefinitionImpl', null); // no caching
$def = $config-&gt;getHTMLDefinition(true);

// add a new tag
$form = $def-&gt;addElement(
 'article', // name
 'Block', // content set
 'Flow', // allowed children
 'Common', // attribute collection
 array( // attributes
 )
);

// add a new attribute
$def-&gt;addAttribute('a', 'contextmenu', "ID");
</code></pre>

However this is clearly a bit of work. Since there are a lot of new HTML5 tags and attributes that had to be registered. And new global attributes should be combinable even with existing HTML 4 tags. (It's difficult to judge from the docs how to augment core rules). So, is there a more useful config format/array structure to feed new and updated tag+attribute+context configuration (inline/block/empty/flow/..) into HTMLPurifier?

<pre><code># mostly confused about how to extend existing tags:
$def-&gt;addAttribute('input', 'type', "...|...|...");

# or how to allow data-* attributes (if I actually wanted that):
$def-&gt;addAttribute("data-*", ...
</code></pre>

And of course not all new HTML5 tags are fit for unrestricted allowance. HTMLPurifier is all about content filtering. Defining value constraints is where it's at. -- <code>&lt;canvas&gt;</code> for example might not be that big of a deal when it appears in user content. Because it's useless at best without Javascript (which HP already filters out). But other tags and attributes might be undesirable; so a flexible configuration structure is imperative for enabling/disabling tags and their associated attributes.

(Guess I should update some research...). But there's still no practical compendium/specification (no, XML DTDs aren't) that suits a HP configuration.

<ul>

<li><a href="http://www.w3.org/TR/html5-diff/#new-elements" rel="nofollow noreferrer">http://www.w3.org/TR/html5-diff/#new-elements</a></li>
<li><a href="http://www.w3.org/TR/html5-diff/#new-attributes" rel="nofollow noreferrer">http://www.w3.org/TR/html5-diff/#new-attributes</a></li>
</ul>

(Uh, and HTML5 is no longer a draft.)
