but first you set the markers array to empty
var markers = [];
leaving nothing to process.
I would suggest naming the array of html elements that you get from
your xml and the array of GMarkers with different names.
Then this rather important line is commented out...
//var point = new GLatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
You don't include the MarkerCluster "library" in your page, so
MarkerManager is undefined.
