README

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.

HTML Purifier can be found on the web at: http://htmlpurifier.org/

Standalone version

For those of you who balk at the possibility of a 100+ includes, we also offer a conveniently packaged single-file version of HTML Purifier. Well, not really, since HTML Purifier does require some auxiliary files in order to work (but they are neatly tucked away in a folder named standalone). Include HTMLPurifier.standalone.php and be done with it!

Installation

Package available on Composer.
