var xmlhttp
function loadXMLDoc()
{

// code for Mozilla, etc.
if (window.XMLHttpRequest)
  {
  xmlhttp=new XMLHttpRequest()
  
  xmlhttp.open("POST","http://demo.sitoext/XML",true);
  xmlhttp.onreadystatechange=xmlhttpChange;
  xmlhttp.send(login_ok);
  }
// code for IE
else if (window.ActiveXObject)
  {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP")
    if (xmlhttp)
    {
    
    xmlhttp.open("POST","http://demo.sitoext/XML",true)
    xmlhttp.onreadystatechange=xmlhttpChange
    xmlhttp.send(login_ok)
    }
  }
}function xmlhttpChange()
{
// if xmlhttp shows "loaded"
if (xmlhttp.readyState==4)
  {
  // if "OK"
  if (xmlhttp.status==200)
    {
var root = xmlhttp.responseXML.documentElement; 
var loginIdElement = root.getElementsByTagName("LoginId")[0]; 
var LoginId = loginIdElement.firstChild.nodeValue;
document.getElementById('log').value = LoginId ;
    }
  else
    {
    alert("Problem retrieving XML data")
    }
  }
}

{
document.location.href="step2.asp?id="+LoginId
