How to fix Complexity

<?php

/**
 * 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.
 *
 * @note Any empty elements will have empty tokens associated with them, even if
 * this is prohibited by the spec. This is cannot be fixed until the spec
 * comes into play.
 *
 * @note PHP's DOM extension does not actually parse any entities, we use
 *       our own function to do that.
 *
 * @warning DOM tends to drop whitespace, which may wreak havoc on indenting.
 *          If this is a huge problem, due to the fact that HTML is hand
 *          edited and you are unable to get a parser cache that caches the
 *          the output of HTML Purifier while keeping the original HTML lying
 *          around, you may want to run Tidy on the resulting output or use
 *          HTMLPurifier_DirectLex
