HTMLPurifier_Lexer |
|---|
Parser that uses PHP 5's DOM extension (part of the core).
In PHP 5, the DOM XML extension was revamped into DOM and added to the core. It gives us a forgiving HTML parser, which we use to transform the HTML into a DOM, and then into the tokens. It is blazingly fast (for large documents, it performs twenty times faster than HTMLPurifier_Lexer_DirectLex,and is the default choice for PHP 5.
