Looping Through XML Data In jQuery

Posted on 2008-11-03
Last Modified: 2013-11-11
I am currently working on a project for work which uses jQuery and XML to fetch and display data obviously from an XML file. I've got about 90% of the project done, but I've hit a roadblock and don't know how to get around it.

Although I am relatively new to jQuery (not Javascript), I've picked up a lot of things myself.

In the XML file there is the following data:

            <title>Blog Title</title>
                  <contributor imageurl="img/rebekah.png" profileurl="">Rebekah</contributor>            
                  <contributor imageurl="img/sarah.png" profileurl="">Sarah</contributor>
                  <contributor imageurl="img/josh.png" profileurl="">Josh</contributor>      
                  <contributor imageurl="img/cassie.png" profileurl="">Cassie</contributor>      

In the XML file each <item></item> is a new blog. At present there are six test blogs in my XML file and I am trying to retrieve the contributor images and then append them to the document via the .append() function. The problem is addressing the specific contributor images in each <item></item>. I have no problem retrieving the first contributor images, but I am having issues getting the other contributor images for other <item></item>'s.

Each item is contained within a case statement. As you can see from the code supplied that it's starting at zero and zero is obviously the first XML element.

Any idea's on how to effectively do this so that contributor images are properly displayed as per the item they are from?

var contrib_count = $('item:eq(1)>contributors>contributor',xml).length;
$(".contributor-container").remove();					$(".contributor_img").remove();		
var i = 0;
while(i < contrib_count)
{							  _contributor_img = $('contributor:eq('+i+')',xml).attr("imageurl");
_contributor = $('contributor:eq('+i+')',xml).text();
							$("#contributors").append('<span class="contributor-container"> <a href="javascript:void(0);"><img src="'+_contributor_img+'" class="contributor_img" /></a> <a href="javascript:void(0);" class="contributor_url">'+_contributor+'</a> </span>');

$('item', xml).each(function(){
        _contributor_img = $(this).attr("imageurl");
        _contributor = $(this).text();
        $("#contributors").append('<span class="contributor-container"> <a href="javascript:void(0);"><img src="' + _contributor_img + '" class="contributor_img" /></a> <a href="javascript:void(0);" class="contributor_url">' + _contributor + '</a> </span>');

Hey sh0e,

Thanks for your prompt resonse again. I tried the code you gave me and it seems to display all contributors and their images.

Seeming as these functions are called from case statements. How do I make it only display the contributors from each item in the XML file? Say for example: Case '1' obviously calls item number 0 in the XML file, how do I make it only pull out the first contributor nodes for the first item?

Sh0e's solution works perfectly. I just realised that for individual nodes you must change the number you want to target:

This code will target all contributor nodes for the first item. You simple replace the eq(0) with the number of the element you want to target.

$('item:eq(0)', xml).each(function(){
        _contributor_img = $(this).attr("imageurl");
        _contributor = $(this).text();
        $("#contributors").append('<span class="contributor-container"> <a href="javascript:void(0);"><img src="' + _contributor_img + '" class="contributor_img" /></a> <a href="javascript:void(0);" class="contributor_url">' + _contributor + '</a> </span>');

Thank you. After a little reading and thought, I worked out how to customise the code to my liking.
