my host upgraded the server and I need to switch to use msxm4 or 6 instead of 2.

Here is my code: can someone help me adapt to version 4 or 6

Set xmlHttp = Server.CreateObject("MSXML2.XMLHTTP.3.0")
xmlHttp.Open "Get", URLToRSS, false
RSSXML = xmlHttp.ResponseText

Set xmlDOM = Server.CreateObject("MSXML2.DomDocument.3.0")

xmlDOM.async = false

Set xmlHttp = Nothing ' clear HTTP object
