Problem beim anzeigen einer XML Datei

<?php
/** 
 * xml2array() will convert the given XML text to an array in the XML structure. 
 * Link: http://www.bin-co.com/php/scripts/xml2array/ 
 * Arguments : $contents - The XML text 
 *                $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
 *                $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. 
 * Return: The parsed XML in an array form. Use print_r() to see the resulting array structure. 
 * Examples: $array =  xml2array(file_get_contents('feed.xml'));  
 *              $array =  xml2array(file_get_contents('feed.xml', 1, 'attribute'));
