HTMLPurifier_AttrTransform Class Reference

Inheritance diagram for HTMLPurifier_AttrTransform:

Public Member Functions
	transform ($attr, $config, $context)
	prependCSS (&$attr, $css)
	confiscateAttr (&$attr, $key)

Detailed Description

Processes an entire attribute array for corrections needing multiple values.

Occasionally, a certain attribute will need to be removed and popped onto another value. Instead of creating a complex return syntax for HTMLPurifier_AttrDef, we just pass the whole attribute array to a specialized object and have that do the special work. That is the family of HTMLPurifier_AttrTransform.

An attribute transformation can be assigned to run before or after HTMLPurifier_AttrDef validation. See HTMLPurifier_HTMLDefinition for more details.
