Save it in a certain format to an XML file?

How does an ASP manipulate XML?
JS part
Creating XMLHTTP Objects
var xobj = new ActiveXObject ("Msxml2.xmlhttp");

Sending data using the XMLHTTP object
Xobj.open ("Post", "save_xml.asp", false);
Xobj.setrequestheader ("Content-type", "Text/xml");
New Xmldom Object
var xdom = new ActiveXObject ("MSXML2. DOMDocument ");
Xdom.async = false;
Xdom.loadxml ("Xxx.xml");
This can be a loading XML file, or it can be a xmldom data object
Send data
Xobj.send (Xdom.xml);
ASP part
' Define MSXML DOM objects
Dim Objresult
Set Objresult = Server.CreateObject ("MSXML2. DOMDocument ")

' Load submit data
Objresult.load (Request)
Objresult.async = False
' Save submit data

Objresult.save (Path)
