jQuery Pass XML Ajax

Question

I have the following jQuery

$.ajax({
    type: "GET",
    url: "http://f.cl.ly/items/0i1V1L1k2F440L1m2Y0G/pointdata.xml",
    dataType: "xml",
    success: parseXml
});

function parseXml(xml) {
    $(xml).find('point').each(function() {
        var lat = $(this).children('lat').text();
        var long = $(this).children('long').text();
        alert(lat + long);
    });
}

Trying to read data from this XML file

You can also see a live jsFiddle here

For some reason, the variables lat and long aren't being assigned for each element. What am I doing wrong? Any help would be much appreciated. Thanks in advance.

The jsfiddle doesn't work because of the same origin policy restriction which forbids you from sending cross domain AJAX requests. Are you sure that you didn't violate this policy in your actual code? So unless your script is hoisted on http://f.cl.ly/ you cannot send AJAX requests to it. — Darin Dimitrov

Updated it, by adding it as a resource, but still no luck. jsfiddle.net/STe25/2 — jacktheripper

@jacktheripper When in doubt, always add an error callback and investigate the Ajax error you get. — Tomalak

@jacktheripper, no you didn't add it as resource. You just added a reference to it. The file is still located on f.cl.ly and your updated jsfiddle doesn't work because you are getting a 404 error. Please use FireBug to see those errors. So as everyone already stated here: you cannot send cross domain AJAX calls. — Darin Dimitrov

3

Your parseXML function works

You're probably violating the same origin policy.
You can't send ajax requests to other domains.

Note that lat + long concats strings so '1' + '2' is '12' not 3.
If you want the result to be 3, parse to int first.
