How to make XML Path dynamic?

Hi, I'm just wondering if we can use dynamic path in the Start XML Session command. I would like to have different configuration files (xml format) called by the same bot. And the bot will be scheduled at two different times. So I was thinking to use wild card (*) in the XML path to make it dynamic. Is that possible?
Please read about xpath. This should help you.
XPath functions can only be used after you actually read and open the XML file, as far as I know. I was actually asking if we can use variables (to make it dynamic) in Automation Anywhere's command of opening xml files (Start XML Session).

Please do share if you have any way to tackle this..
