3  Requires PHP5, uses built-in DOM extension.
4  To be used in PHP4 scripts using DOMXML extension: allows PHP4/DOMXML scripts to run on PHP5/DOM.
5  (Optional: requires PHP5/XSL extension for domxml_xslt functions, PHP>=5.1 for XPath evaluation functions, and PHP>=5.1/libxml for DOMXML error reports)
6 
7  Typical use:
8  {
9  if (PHP_VERSION>='5')
10  require_once('domxml-php4-to-php5.php');
11  }
