php xml dom

[calabiyau]

I'm trying to delete a node from an xml file.  The xml file is structured as follows

<pages>

<page>

<script_files>

<script>

<script_file></scriptfile>

<script_name></script_name>

</script>

</script_files>

</page>

</pages>

 

and the code i've been trying is

 

<?php
$new_page = $_POST['page'];
$script_file = $_POST['script_file'];



$xml = new DomDocument('1.0'); 
$xml->load('../database/content_db.xml'); 


$sub_doc = $xml->getElementsByTagName('page')->item($new_page);

$scripts = $sub_doc->getElementsByTagName('script_files')->item(0);

$spec_script = $scripts->getElementsByTagName('script')->item($script_file);



$olduser = $scripts->removeChild($spec_script);  

$xml->save("../database/content_db.xml"); 

?>

 

Thing is I had this sort of working with similar code but have gotten lost along the way.  Anyone familiar with this sort of work that could send me in the right direction?  Thanks
