and after long research found how values of nodes using foreach loop, there way names? need can parse xml magicparse (http://www.magicparser.com/)

example input:

<?xml version="1.0"?> <root attribute="example_attribute">   <node 1>     <nested node>     <nested node>   </node 1>   <node 2>   </node 2> </root>

<?php  $xf = file_get_contents($xmlfilename); $xml = simplexml_load_string($xf);  displaynode($xml, 0);  function displaynode($node, $offset) {      if (is_object($node)) {         $node = get_object_vars($node);         foreach ($node $key => $value) {             echo str_repeat(" ", $offset) . "-" . $key . "\n";             displaynode($value, $offset + 1);         }     } elseif (is_array($node)) {         foreach ($node $key => $value) {             if (is_object($value))                 displaynode($value, $offset + 1);             else                 echo str_repeat(" ", $offset) .
