Xml w/ dynamic text - not showing online

I have a photogallery that uses xml to get photos and a text description. When I preview the file locally in Firefox, the description shows up, but when I view the page live, there’s no text. The text also shows up in IE (but who uses that anymore?). Here’s the page I’m refering to: http://www.peregrineimaging.com/gallery/index.html.

Here’s the xml:

    <description><p align="center"><a href="http://www.istockphoto.com/file_closeup.php?id=2130029refnum=ccahill" target="_new">iStock #2130029</a></p></description>

What would cause the text not to show online, when it does locally?
