Functions called from  include:


 * function preprocessToObj - preprocesses wikitext and returns a document tree, also called DOM tree. It calls:
 * function preprocessToXml - parses the wikitext with respect to double braces, triple braces  , and double rectangular brackets ... , and also finds the pipes | and the equals signs =. The result is the DOM tree.
 * function expand - produces the expanded wikitext from the DOM tree. It performs double-brace expansion, calling function braceSubstitution in Parser.php, and triple-brace expansion, calling function argSubstitution in Parser.php.
