Your downloadUrl is different from that in the tutorial.
Yours:
function downloadUrl(url, callback) {
...
callback(request.responseXML, request.status);

Tutorial:
function downloadUrl(url,callback) {
...
callback(request, request.status);

Then in your code you have (and the tutorial has) this:
      downloadUrl("phpsqlajax_genxml3.php", function(data) {
        var xml = data.responseXML;

Your code is trying to access request.responseXML.responseXML, it
doesn't exist.
