jQuery parse xml not returning data in ie

I am parsing an xml file after a ajax call to 'get' the xml file. I am trying to return one of the nodes (using the find method). however it will not return the value in ie - fine in firefox. i am doing a alert to test the value and it just comes back blank. Below is the code:

function autoFeedGetter () {
 $('#notifyBox').empty();
  $.ajax ({
  type: "GET",
  url: "actual url removed",    
  datatype: "xml",
  success: checkNoteDate 
  }); 
  };
 // get time date saved to fullDateTime Variable 

 funct开发者_JAVA百科ion checkNoteDate (xml) {
  var noteDate = 'Not';
  var lastSplit = 'Not'; 
  // get published date from feed
  noteDate = $(xml).find('entry published:eq(0)').text();    
  alert(noteDate);
}

The problem seems to be with this method - noteDate = $(xml).find('entry published:eq(0)').text();

however i have tried various other versions of this including: noteDate = $(xml).find('entry:first published').text();

if any one has any info will be most appreciated.

example xml

sensitive data removed - i am able to successfully parse the data in full but not retrieve one element - e.g. i am looking for the first published date

Looking at andrea varnier's reply at the bottom of http://groups.google.com/group/jquery-en/browse_thread/thread/adb2b047f3761179?pli=1, it would appear that IE doesn't work with xml files loaded up from your local machine. There is also a solution postage there if you don't want to rely on it just working when you deploy your page:

success: function(xmlData){ 
var data; 
if ( typeof xmlData == 'string') { 
    data = new ActiveXObject( 'Microsoft.XMLDOM'); 
    data.async = false; 
    data.loadXML( xmlData); 
} else { 
    data = xmlData; 
}

So it looks like IE has left the XML as a single string, so that method loads it up into an xml document object. You can then use jQuery on that object.
