XML & PHP

Apple has a nice iTunes RSS feed generator. I want to use its output to make a simple web page with all the latest album releases etc.  I have the following test setup: http://54.88.218.38/test.php. I am running into issues when I try and access the objects/elements (not sure what they are called) that have a “:” in the name. Here is the raw output: https://itunes.apple.com/WebObjects/MZStore.woa/wpa/MRSS/newreleases/sf=143441/limit=50/rss.xml

<itms:artist>  and <itms:coverArt height=”100″ width=”100″> are elements I am trying to access. PHP pukes on the “:” no matter how I try and escape the character.

 

Any suggestions?

Here is the code with Chris’ suggestions:
