Accessing xml with colon in tag name

[lr]

Hi guys,

 

I have xml that looks like:

 

<item>

<title></title>

<link></link>

<description></description>

<dc:date>2011-02-27T16:42:31-05:00</dc:date>

</item>

 

 

I can access title, link, and description just fine.  But how do I access a tag that has a colon?

 

I tried this:

 

$x = new SimpleXmlElement($content);
$entry = $x->item;

$entry->children('dc', true)->date;

 

Thanks for looking.
