/*

        Requires PHP5, uses built-in DOM extension.

        To be used in PHP4 scripts using DOMXML extension: allows PHP4/DOMXML scripts to run on PHP5/DOM.

        (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)

        Typical use:

        {

                if (PHP_VERSION>='5')

                        require_once('domxml-php4-to-php5.php');

        }
