DOMXPath query error , shows nothing

I am using this code to get some metal name(e.g:copper,aluminium) from this site : http://www.kitcometals.com/ . this names are located at the left side of the page in a table named live spot prices.

here is my code :

<?php
$url = "http://www.kitcometals.com/";
$html = file_get_contents($url);
$dom = new DOMDocument();
$dom->loadHTML($html);
$xp = new DOMXPath($dom);

$qs = $xp->query("//table[@dwcopytype='CopyTableRow']/tbody/tr[@class='spot']/td[@class='menuB']");
foreach($qs as $q)
{
    echo $q->textContent."<br>";
}
?>

I have tested this XPath in google chrome's Xpath app . It has just worked fine showing every metals name in that table.showing this:

Copper Nickel Aluminum Zinc Lead Uranium

But it's not working in PHP code.Would anybody please figure out the problem ??

You have tested the xpath query against the "runtime" dom of the browser. But there is no tbody element in the actual document. Try

//table[@dwcopytype='CopyTableRow']/tr[@class='spot']/td[@class='menuB']
