htmlpurifier/library/HTMLPurifier/ChildDef/Chameleon.php
Edward Z. Yang b1b3377b9c [1.3.0] Huge upgrade, (X)HTML Strict now supported
+ Transparently handles inline elements in block context (blockquote)
! Added GET method to demo for easier validation, added 50kb max input size
! New directive %HTML.BlockWrapper, for block-ifying inline elements
! New directive %HTML.Parent, allows you to only allow inline content
- Added missing type to ChildDef_Chameleon
. ChildDef_Required guards against empty tags
. Lookup table HTMLDefinition->info_flow_elements added
. Added peace-of-mind variable initialization to Strategy_FixNesting
