Parse XML with PHP and XMLReader

Question

I\'ve been trying to parse a very large XML file with PHP and XMLReader, but can\'t seem to get the results I am looking for. Basically, I\'m searching a ton of information

Edit: Oh you want to return the parent chunk? One moment.

Here's an example to pull out all of the postalCodes into an array.

  Grande Gables at The Terrace
  Grande Communications
  
   635
  
  
   11111
   22222
   33333
   78746
  
  Austin
  
   
    002
   
   
    003
   
  
  
   
    Thorndale
    Milam
    TX
   
   
    Thrall
    Williamson
    TX
   
  
 ';

$dom = new DOMDocument();
$dom->loadXML($string);

$xpath = new DOMXPath($dom);
$elements= $xpath->query('//lineups/headend/postalCodes/*[text()=78746]');

if (!is_null($elements)) {
  foreach ($elements as $element) {
    echo "
[". $element->nodeName. "]";

    $nodes = $element->childNodes;
    foreach ($nodes as $node) {
      echo $node->nodeValue. "\n";
    }
  }
}

Outputs:

[postalCode]78746
