Get nodeValue with PHP

[judejitsu]

Hi guys, I have this chunk of code, I need to find out why it doesn't find the nodeValue for some parts of my HTML file.

 

<?php
$string = '

return $ret;

Problem is, the $pn variable doesn't display the value instead jumps to the next <td> which contains the QTY value.
