I've started teaching myself Ajax, and I was wondering if it's possible to get around having
&lt;script src="http://www.uuuq.com/fixstats.php"></script>
added onto the PHP page that returns from an XML request.

Should I just filter it from the string? Or is there another workaround?

For anyone wondering, this is the client side JS

CODE
function ajaxFunc() {
  var xmlHttp;
  try {
    // FF, Opera 8+, Safari
    xmlHttp=new XMLHttpRequest();
  } catch (e) {
    // IE
    try { // IE 6+
      xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    } catch (e) {
      try { // IE 5.5+
        xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
      } catch (e) {
        alert("Your browser doesn't support AJAX!/nYou fail at life.");
        return false;
      }
    }
  }

  xmlHttp.onreadystatechange=function() {
    if (xmlHttp.readyState==4) {
      document.newItemForm.time.value=xmlHttp.responseText;
    }
  }
  xmlHttp.open("GET","time.php",true);
  xmlHttp.send(null);
}
