Variable filename in xml tag in asp

Hello

I'd appreciate any help with a problem i'm facing.

I'm looking for a way to include the results of an xml file in an asp document. The catch is that the name (and path) of the xml file is not constant. It is constructed within a javascript function and placed in a session variable. After a lot of search in google and various forums i know (including this), i couldn't find a way to use it in an xml tag.

For instance, i have placed the following statement in a .asp file:

<xml id="xmldso" src="/Dir1/test.xml" async="false"></xml>

I would like somehow to replace the "/Dir1/test.xml" fixed statement with a session variable containing the actual filename.

TIA for any help.

Why can't you just use Response.Write to echo the variable name?
