[snipped lots of other xmlstr = xlmstr + ...]
Don't do that. That's wasting a LOT of performance. NEVER build up
a big string with a zillion s = s + ... (or s += ... which turns out
to be the same thing). You could do:
xmlstr = ( "<?xml version='1.0'?>"
+ "<config"
+ "last_server=\"0\""
and so on, just close the ) when done to terminate the logical line.
Or, more generally:
xmlpieces = ["<?xml version='1.0'?>"]
xmlpieces.append("<config")
xmlpieces.append("last_server=\"0\"")
and so on, then, when done:
xmlstr = ''.join(xmlpieces)
Either approach is vastly preferable.

You need the win32all extensions (or ActiveState's ActivePython,
that comes with win32all already added) and the Windows Scripting
Host (WSH) component from Microsoft. See
http://aspn.activestate.com/ASPN/Mail/Message/activepython/544878
for a good example of using the SendKeys method of the WSH object
WScript.Shell.

It would override it only if it was a method of a class
inheriting from file, and only for instances of that class.
