get index value of an element from XML using jQuery

New to jQuery, I have a script that returns data from an XML file. What I need is the index number of the element returned. I know I can retreve a single element with this 

name = $("sitelist:eq(1)",data).text();

but in my script I need to know each element position for the displayed data. something like position = $(data,eq).value .Can anyone help please . 

$(document).ready(function () {

    $.ajax({
        type: "GET",
        url: "sites.xml",
        dataType: "xml",
        success: displayXml
    });

    function displayXml(data) {
        $(data).find("course").each(function () {
            var name = $(this).find("sitelist").text();
            var line1 = $(this).find("address1").text();
        });
    }
}); // doc ready

I'm not sure which node you need the index for, but if it is the course that you're iterating over with .each() you can get the index of each iteration from .each()

 $(data).find("course").each(function( idx ) {
      alert( idx ); // will alert the index of the current "course"

      var name = $(this).find("sitelist").text();
      var line1 = $(this).find("address1").text();
 });

If there's some other situation, you could try using the .index() method to get the index of the node from among its siblings. It requires jQuery 1.4 or later.

As in:

var $sitelist = $(this).find("sitelist");
var index = $sitelist.index();
var name = $sitelist.text();
