Detailed Description

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, 1->postFilter.

Note

Methods are not declared abstract as it is perfectly legitimate for an implementation not to want anything to happen on a step
