Spry displaying in Firefox & Safari, but not in IE

Question

Ok, so I was trying to replicate one of the demos: http://labs.adobe.com/technologies/spry/demos/rssreader/index.html
Except that we're running on a LAMP platform which meant I had to rerwite the ColdFusion into PHP. I'm hoping the PHP isn't the issue, seeing as this wouldn't be the forum for correcting that problem.
Here's the page I'm working on: http://www.darton.edu/ol-or/new.php
It works just fine in Firefox & Safari, but when I get to IE, I get the "Failed to load feed items!" error.
I can read the feeds in IE, but for some reason it won't display them.
The core of the feeds.php I wrote:
$xmlstr = trim(file_get_contents('LiveFeeds.xml'));
$mydoc = new SimpleXMLElement($xmlstr);
foreach($mydoc->feed as $feed)
  if($feed['id'] == $id)
   $url = $feed['url'];
   $curl_handle=curl_init();
   curl_setopt($curl_handle, CURLOPT_URL, $url);
   curl_setopt($curl_handle, CURLOPT_HTTPGET, TRUE);
   curl_setopt($curl_handle, CURLOPT_HTTPHEADER, array ("Content-type: text/xml; charset=utf-8"));
   /*$buffer = */ return curl_exec($curl_handle);
   curl_close($curl_handle);
   //return $buffer;
Firefox and Safari aren't having a problem at all, everything is processing correctly. I thought, after reading some in the forum that the Headers were the issue, but as far as I can tell, the cURL HTTP Header feature is working as it's supposed to.
I feel like I'm beating my head against a brick wall at this point.
I just need guidence at this point, at least a shove in the right direction would be helpful.
Many thanks in advance.

The XML file seems to be in order.
I do notice that IE has a problem with SpryData.js which points to interference from other JS. For a start, place xpath.js after SpryData.js.
If this does not solve the problem, try placing both of the above files before any other JS files.
