Good guess! ;)

Sure. Thanks! Would you prefer exactly for this method over the method posted by Kent Johnson
few minutes ago?

Am I so deperately fighting the language? No-one here on the list needs to set hundreds
variables at once somewhere in their code? I still don't get why:

"include somefile.py" would be that non-pythonic so that it's not available, but
I have already two choices how to proceed anyway. Thanks. ;)

Now have to figure out how to assign them easily into the XML tree.
