Read xml file data from external http url

Question

I want to read a xml file generated from Drupal 7 using JQuery and Ajax.

When I type the http url link in url:' ' the Ajax function doesn't retrieve any data.

When I type my xml file as a local file (without http url) the Ajax function works normally.

The Ajax code is:

$(document).ready(function () {
    $.ajax({
        type: "GET",
        url: "any http url that contains xml file",
        dataType: "xml",
        success: xmlParser
    });
});

function xmlParser(xml) {

$('#load').fadeOut();

$(xml).find("movie-info").each(function () {

    $(".main").append('<div class="book"><div class="title">' + $(this).find("title").text() + '</div><div class="description">' + $(this).find("field_genre").text() + '</div><div class="date">Published ' + $(this).find("field_poster").text() + '</div></div>');
    $(".book").fadeIn(1000);

});
