Post XML to Servlet through JavaScript and reveive info back

Question

There's a post in this forum before, but anyone know how to do this:
=========================================
MSIE5 + will let you post an XML string to a servlet. It must be done from javascript. The same javascript can also receive an xml string back from the servlet, parse it, and update dom objects in the browser, independenty of a an http post.
You can use this technique to populate ddlb based on events in the browser, or do real-time validations from the database. It works just fine, is quite fast, but is MSIE specific. If another brower is used, you must handle it some other way.
=========================================
I will use IE only.
Any help will be highly appreciated!

Thanks for your response, ddossot!
I also got something from our Microsoft team, post here to share with others who have interest in this topic. It's interesting to see IE talk with Servlet in XML, especially within a LAN.

I did find a couple of things. Not sure if it is exactly what you are looking for. Let me know if it works.
function submitAsXML() {
     var theXML = document.myform.txtInXML.value;
var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
     var url = document.myform.txtURL.value;
try {
xmlhttp.open("POST", url, false);
} catch(e) {
xmlhttp.open("POST", url, false);
xmlhttp.Send(theXML);
     var xmlResp = xmlhttp.ResponseText;
     document.myform.txtOutXML.value = xmlResp;
