xml input sanitizing method in standard lib?

[Petr Muller]

Hi,

Is there some method provided in python standard library to sanitize
strings used as input to xml documents? (=remove form-feeds and whatever
else). I've searched docs and google, found only 4Suite project. I
cannot rely on something not in standard lib, so I'm wondering if I've
just overlooked something in the docs to this (imo) important task...
