Demo:

 ?phprequire XMLParser.class.php $xmlfile = file.xml $xmlstring = ?xml version= 1.0 encoding= utf-8 ?  xmlroot  status 1000 /status  info /info  result id 100 /id  name fdipzone /name  gender 1 /gender  age 28 /age  /result  /xmlroot echo pre $xml_parser = new XMLParser();echo response xmlfile/r/n list($flag, $xmldata) = $xml_parser- loadXmlFile($xmlfile);if($flag){print_r($xmldata);echo response xmlstring/r/n list($flag, $xmldata) = $xml_parser- loadXmlString($xmlstring);if($flag){print_r($xmldata);echo /pre ?
