The XML feed for my autocomplete is on another server. Is there a client side (javascript) method of getting this XML document?

I know I can create a proxy with php, jsp, etc.. but I need to do it all client side. This is how I call the file now that only works if it is on the same domain:

```
function callAjax(url) {
  $.ajax({
        url : url,
        dataType : "xml",
        success : function(xmlResponse) {
              totalrec = $("TOTALREC", xmlResponse).text();
            $.merge(data1, $("ROW", xmlResponse).map(returnResults).get());
        }// end of success
  });

```
