Parse RSS Feed With Unique Elements

Question

I have used PHP with simplexml to parse RSS using standard elements before like <title> <pubDate> etc. But how would I parse something custom to the feed like <xCal:location> or <xCal:dtstart> that uses an xCal data element?

Something like $item->xCal:dtstart will error out. How would I collect this data element?

A sample of a feed like this: http://www.trumba.com/calendars/vd.rss?mixin=236393%2c236288

Try like this:

$feedUrl = 'http://www.trumba.com/calendars/vd.rss?mixin=236393%2c236288';
$rawFeed = file_get_contents($feedUrl);
$xml = new SimpleXmlElement($rawFeed);

$ns = $xml->getNamespaces(true);

//print_r($ns);
$xCal = $xml->channel->children($ns['xCal']);
echo ($xCal->version)."<br />";

foreach($xml->channel->item as $item)
{
    //print_r($item);
    $itemxTrumba=$item->children($ns['x-trumba']);
    echo $itemxTrumba->masterid."<br />";
}
//print_r($xCal);
