xmlhttprequest continuous loop

xmlhttprequest continuous loop

(OP)
I am trying to get this script to loop and keep getting error message "Object Expected"  Anyone have any ideas?

Here's the code:

<html>
<head>
<script language="javascript">
function getData()
{
  xmlHttp = new XMLHttpRequest();
  xmlHttp.onreadystatechange = processData;
  xmlHttp.open("GET","xmltest.xml",true);
  xmlHttp.send(null);
  xmlDoc = xmlHttp.responseXML;
}
function processData()
{
    document.write(xmlDoc.getElementsByTagName("firstname")[0].childNodes[0].nodeValue);
    setTimeout(getData(),3000);
}
</script>
</head>
<body onLoad="getData()">
</body>
</html>

RE: xmlhttprequest continuous loop

I'd try to show what xmlDoc has when you enter the processData function.

Cheers,
Dian
