php domdocument get node value where attribute value is

Say my XML looks like this:

<record>
  <row name="title">this item</row>
  <row name="url">this url</row>
</record>

Now I'm doing something like this:

$xml = new DOMDocument();
$xml->load('xmlfile.xml');

echo $xml->getElementByTagName('row')->item(0)->attributes->getNamedItem('title')->nodeValue;

But this just gives me:

NOTICE: Trying to get property of non-object id

Does anybody know how to get the node value where the "name" attribute has value "title"?
