Im creating a script that pulls xml data from a central server, then stores it locally to be read. The script will resides on 100's of different servers. Some of these servers have php4, some have php5, some have domxml, some have simplexml, some have regular xml... Ive done what i needed to in domxml and in simple xml... My question is does anyone have a easy way to match the following examples...

CODE EXAMPLE 1: SERVER WITH SIMPLEXML RUNS...
  $domaininfo = simplexml_load_file($localxmlfile);

CODE EXAMPLE 2: SERVER WITH DOM XML RUNS...
  $xml = file_get_contents($localxmlfile);
  $doc = domxml_open_mem($xml); //(PHP 4 >= 4.2.0)
  $domaininfo = xmlnode2array($doc->root());

I need domaininfo to be an array containing the xml data... the xml data has children, its not just one level deep... heres an example of the data being pulled...

EXAMPLE XML:
<domaininfo>
<nid>378</nid>
<title>Best+Web</title>
<created>1212617890</created>
<changed>1212799071</changed>

i looked at that class and used part of it to write my own... i added lines to the start and data functions to check for the term page since i had more that 1 "pages" and stored them as their own array 0,1,2,3,4, etc... otherwise each page just overwrites the last one in the array since the key would be the same...  my solution is as follows....

$xmlArray=array();
startParser($localxmlfilepath);
print_r($xmlArray);

// Starts the XML parser
   function startParser($xmlFile)
   {

      $xmlParser = xml_parser_create();

      xml_parser_set_option($xmlParser, XML_OPTION_CASE_FOLDING, false);
      xml_set_element_handler($xmlParser, startElement, endElement);
      xml_set_character_data_handler($xmlParser, characterData);

      $fp = fopen($xmlFile, "r");

      while($data = fread($fp, filesize($xmlFile))){
         xml_parse($xmlParser, $data, feof($fp));}

      xml_parser_free($xmlParser);
     

   }

   // Sets the current XML element, and pushes itself onto the element hierarchy
   function startElement($parser, $name, $attrs)
   {

      global $currentElements, $itemCount;

      array_push($currentElements, $name);
      if($name == "page"){
      $itemCount += 1;
      }

   }

   // Checks and adds XML elements to array
   function characterData($parser, $data)
   {

      global $currentElements, $xmlArray, $itemCount;

      $currentCount = count($currentElements)-1;
      $parentElement = $currentElements[$currentCount-1];
      $thisElement = $currentElements[$currentCount];

      if($parentElement == "page"){
         $xmlArray[$parentElement][$itemCount-1][$thisElement] = $data;
      }else{
        $xmlArray[$parentElement][$thisElement] = $data;
      }
         
   }

   // If the XML element has ended, it is poped off the hierarchy
   function endElement($parser, $name)
   {

      global $currentElements;

      $currentCount = count($currentElements)-1;
      if($currentElements[$currentCount] == $name){
         array_pop($currentElements);}

   }
