I have the following code...
<%
Response.Expires = -1000
Dim x1
set x1 = Server.CreateObject("MSXML.DOMDocument")
x1.loadXML("<P><T a='1' n='ttt'/><T a='2' n='yyy'/></P>")
dim xmlTempNode
set xmlTempNode = x1.selectSingleNode("//T[@a='4']")
if (xmlTempNode is Nothing) then
Response.Write "Does not exists..."
else
Response.Write "Exists"
Response.Write " value is:"
Response.Write xmlTempNode.attributes.getNamedItem("n").text
end if
set xmlTempNode = nothing
set x1 = nothing
%>
This code seems to be ok, when I execute it for the first time.
If I change,
set xmlTempNode = x1.selectSingleNode("//T[@a='4']")
to
set xmlTempNode = x1.selectSingleNode("//T[@a='2']")
There is no effect in the code.
But then if I modify the XML (say by modifying an attribute value)
it shows the result correctly.
Thanks,
Babloo

Hi Babloo,
this has always worked for me:
Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache"
Response.Expires = -1
BTW in your XPath, using // is a bad habit to get into because it can be a very expensive operation (not in XML as small as your example here, though). Its much better to use the full path if you know it, e.g. /P/T[@a='4']
