Looks like the static function you called (DOMDocument::load - check the capitalisation) is not returning you a DOM object for some reason, e.g. perhaps it can't find userdb.xml. I suggest you check the contents of $doc  to check that it is a valid instance of a DOM object. var_dump($doc) will show you what's there. The user notes on this page suggest ways of checking for errors:

This was my point. Your example code can't tell you that this is so. If the DOM library was not installed, you would get an error on your load call because that's form the same library, therefore, you do already have the DOM library installed and working. Check the return value of DOMDocument::load before you try and use it. Like in the example I pointed you at:

$doc = DOMDOcument::load("userdb.xml");
if (!$doc) {
  print "Error creating DOM instance";

Try that first, and if it still doesn't work, start investigating further.

Mainly you need to put the php_domxml.dll in your PHP/extensions directory. For more detail, read this:
