Yes, I think you should be able to apply the logic to TCL commands, since TCL supports regular expressions. I don't know anything about the TCL regexp command, so cannot help with details. Any chance TCL can call sed?
Yes, you can get the ip address, minus the c= part, by moving c= outside of the saved group, as follows:

Problem is I'm unable to find the ipaddress of the xterm user. It just shows the display as "localhost".
