HTML filter that is HTML5 compliant

Question

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

HP can be configured to recognize new tags with:

// setup configurable HP instanc

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 https://github.com/xemlock/htmlpurifier-html5 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 HTMLPurifier_Config with HTMLPurifier_HTML5Config:

$config = HTMLPurifier_HTML5Config::createDefault();
$purifier = new HTMLPurifier($config);

$clean_html5 = $purifier->purify($dirty_html5);
