 </item>


IF I Try to get the first node using :first, it doesn't work at all
var thumb = $(this).find('[nodeName=media:thumbnail]:first)').attr('url');

IF I Try to get the first node using :eq(0) , I get the URL as undefined. 

var thumb = $(this).find('[nodeName=media:thumbnail]:first)').attr('url');

Here is my complete code. 


 $('#output').empty();
 $(xml).find("item").each(function()
 {
 
 var title = $(this).find('title').text();
 var pubDate = $(this).find('pubDate').text();
 var description = $(this).find('description').text();
 var thumb = $(this).find('[nodeName=media:thumbnail]:eq(0))').attr('url');
 var listItem = $('<li><img src=' + thumb + ' /><br/>' + title + pubDate + '<br/>' + description + '</li>'); 
 $("#output").append(listItem);
 });


Thanks
