This line:

$xml_numbers = $xml->getElementsByTagName('numbers');

should be:

$xml_numbers = $xml->getElementsByTagName('numbers')->item(0);

Note, that getElementsByTagName() will always return an XMLNodeList Object, not a single node - even if just a single element was found, like in your case. You need to explicitly address the first element of that list using ->item(0).
