I can't tell you about IDLE related stuff (I don't use it myself), but 
FWIW, you have a problem with main()'s 'arg' param : you use it like this:

 >     parser.parse(args[0])
but pass it like this:
 >     main("\\Iceman\propod\flash\xml\webService\XmlData\Authors\Heidi")

The first problem is that:
already raises an exception ('ValueError: invalid \x escape').

The second problem is that somestring[0] returns the first characted of 

First correct your code, then see what happens. And eventually, find a 
better tool than IDLE...
