I hate DOM model !
so I wrote dom2array simple function (simple for use):

function dom2array($node) {
  $res = array();
  print $node->nodeType.'<br/>';
  if($node->nodeType == XML_TEXT_NODE){
      $res = $node->nodeValue;
  }
  else{
      if($node->hasAttributes()){
          $attributes = $node->attributes;
          if(!is_null($attributes)){
              $res['@attributes'] = array();
              foreach ($attributes as $index=>$attr) {
                  $res['@attributes'][$attr->name] = $attr->value;
              }
          }
      }
      if($node->hasChildNodes()){
          $children = $node->childNodes;
          for($i=0;$i<$children->length;$i++){
              $child = $children->item($i);
              $res[$child->nodeName] = dom2array($child);
          }
      }
  }
  return $res;
}
