php and xml, a better way to read all nodes

Question

I have this xml, and I cannot find a way to read all of this data with PHP. I have tried the simple:

$xmlDoc->load("data/xml/page.xml");

with all the rest, but in a way or in another, I cannot find a way to read the name of the gallery (in this xml) and the url/attribute of the image

<DOCUMENT>  <galleries_group>
<GROUP id="main_gallery_group">
  <DATA id="category_name">
    <CONTENT><![CDATA[Black & White]]></CONTENT>
  </DATA>
  <GROUP id="sub_gallery_group">
    <DATA id="gallery_name">
      <CONTENT><![CDATA[WOMENS]]></CONTENT>
    </DATA>
    <GROUP id="sub_gallery_image">

You might want to try something like this and adjust the XPath to your needs.

<?php
$xmlDoc = simplexml_load_file('data/xml/page.xml');
$result = $xmlDoc->xpath('/DOCUMENT//GROUP/DATA/CONTENT');
while (list(, $node) = each($result)) {
    echo $node;
}
?>

Watch out though, because the XML you originally posted is not wellformed. <galleries_group> in line 1 is either not closed properly or completely dispensable.
