PHP Class HTMLPurifier_Lexer_DOMLex, yii

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.
