Docs For Class HTMLPurifier_Lexer

Description

Our in-house implementation of a parser.

A pure PHP parser, DirectLex has absolutely no dependencies, making it a reasonably good default for PHP4. Written with efficiency in mind, it can be four times faster than HTMLPurifier_Lexer_PEARSax3, although it pales in comparison to HTMLPurifier_Lexer_DOMLex.

todo: Reread XML spec and document differences.
