Documentation is available at Filter.php
* Represents a pre or post processing filter on HTML Purifier's output
* Sometimes, a little ad-hoc fixing of HTML has to be done before
* it gets sent through HTML Purifier: you can use filters to acheive
* this effect. For instance, YouTube videos can be preserved using
* this manner. You could have used a decorator for this task, but
* PHP's support for them is not terribly robust, so we're going
* to just loop through the filters.
* Filters should be exited first in, last out. If there are three filters,
* named 1, 2 and 3, the order of execution should go 1->preFilter,
* 2->preFilter, 3->preFilter, purify, 3->postFilter, 2->postFilter,
* @note Methods are not declared abstract as it is perfectly legitimate
* for an implementation not to want anything to happen on a step
* Name of the filter for identification purposes
* Pre-processor function, handles HTML before HTML Purifier
public function preFilter($html, $config, $context) {
* Post-processor function, handles HTML after HTML Purifier
public function postFilter($html, $config, $context) {
