How to link checkboxes to XML file

I am new to XML and web development in total, so please bare with me - I am learning, so this may be super easy, but I have spent hours struggling with this.

Background on what I am building: I am creating a form which links to an XML file. On the form there are checkboxes, I want to pull the 'text' for the checkbox from the xml file.

The code I have for the checkboxes is:

  $('.cb').on('click', function () {
            nextID = $(this).attr('target');
            nextEl = $('#' + nextID);

            if (!nextEl.is('visible')) {
                nextEl.show();
            }
        });

and the code I have been playing with:

    var XML_PATH = "xml/test.xml";
$(function(){
    $.ajax({
        type: "GET",
        url: "XML_PATH",
        dataType: "xml",
        success: function(xml){
            $(xml).find('cb').each(function(i){
                var ou = $(this).text();
                $('#cb').append("<input class='cb' value='"+ id +"'>"+ root +">");
            });
        }
    });
});

I have fiddled with various bits of code to try and link the xml file, with no joy. Just hoping for some guidance and advice on how to go about this. I could be looking at the completely wrong thing. I've also been unable to find an example I can use for guidance.

Thank you very much for any guidance/advice given.
