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];

   }

  
}
?>
