I have to read latitudes and longitudes from an xml file and plot it on the map. Below is js:

function initialize() {
        var latlng = new google.maps.LatLng(18.73033, 72.87844);

        var mapOpts = {
            zoom: 3,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP,
        };

        var map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOpts);

        downloadUrl("output.xml", function (data) {
            var xmlDoc = xmlParse(data);
            var records = xmlDoc.getElementsByTagName("Table");


            for (var i = 0; i < records.length; i++) {
                var rec = records[i];


                var lat = parseFloat(rec.getAttribute("lat"));
                var lng = parseFloat(rec.getAttribute("long"));

                var pt = new google.maps.LatLng(lat, lng);
                alert(pt)


                createMarker(pt, map);
            }
        })
    }

But nothing is being plot. On applying alert i found nothing is comming in lat, lng. That means the java script is not getting 'output.xml'. Please tell me where to store xml file.
