A simple function that uses this method to print the nodes it finds in an xml document. Improvements welcomed.

<?php
function printTags($tag){

 
$node = $this->doc->getElementsByTagName($tag);          
   for(
$c = 0; $c<$node->length; $c++){
    
$text[$c] =$this->doc->saveXML($node->item($c));
     echo
$text[$c];

   }

 
}
?>
