The documentation for PHP 5's DOM functions isn't at its most helpful yet, so I thought an example of how to use 'removeChild' wouldn't go amiss.

Assuming first that you have some DOMDocument XML in a variable called $xml, that may look something like this:

<root>
  <labels>
    <title>My title</title>
  </labels>
</root>

The first thing to do is to get a handle on the node you want to remove. We're going to remove the node named 'title':

$node=$xml->getElementsByTagName("title")->item(0);

Then, simply remove $node from its parent:

$xml->getElementsByTagName("labels")->item(0)->removeChild($node);

Not too much to it at all.
