Ajax XML请求失败

Question

I'm trying to load a remote xml file so I can parse it and return some results, but this Ajax GET request keeps failing. See it on a jsfiddle here. Note: this also fails if you use dataType: 'xml'

$(function() {
    $.ajax({
        type: "GET",
        url: "http://ultrasoundoftheweek.com/wp-includes/wlwmanifest.xml",
        dataType: 'text',
        cache:'false',
        success: function(data) {
            alert("yes");
        },
        error: function(xhr, status) {
            alert("no");
        }
    });
});
