SimpleXML broke while I was sleeping.

So I had a code project that took the name of a piece of equipment in World
of Warcraft - pulled the XML from WoWhead and pulled the database item
number from the XML file. It worked for a long while and the code simply sat
around not being used. I went back to pull the project out for inclusion in
something new and it no longer works.

I wasn't terribly comfortable with XML to begin with so I'm not sure what
has changed - but here is the code the worked for so long:

function item_num_from_xml($url)
{
    $xml = new SimpleXMLElement(rawurlencode($url), NULL, TRUE);
    $item_num = $xml->items->item[id];
    return $item_num;
}

        $xml_link = "http://www.wowhead.com/?search=".str_replace(" ", "+",
$item)."&xml";
        $item_num = item_num_from_xml($xml_link);
        $itemlink = "http://www.wowhead.com/?item=".$item_num;

This is the error message I now get:
*Warning*: SimpleXMLElement::__construct()

First person to point out what stupid mistake I'm making can mock me for a
long time.
