Php dom/xml difficulty ARGHHH

trying to wrap my head around why i cant access the textContent of the firstChild element in an xml file using php’s dom… will return the element id’s however… does anyone know why???

xml file:

<?xml version="1.0"?>
<Title>Massive Stars Can Grow Near Black Holes</Title>
<Title>Researchers Study Changes in Hurricanes</Title>

$dom = new DOMDocument;

//$Items = $dom->documentElement->getElementsByTagName('Item');
foreach ($Items as $item) {
		print $item->firstChild->textContent;
		print '<br />';
		if($item->firstChild->textContent == '20051019')
print '<br /> done.';
