multiprocessing just mimicks the threading module here, see
http://bugs.python.org/issue1230540 . Why do you need excepthook in the

You can perfectly simulate it by wrapping the root method (target in
your example) in a try .. catch:

Hello Python friends, I have to validate some xml files against some xsd

Hey
I was surprised not to find any way to list all protocol names listed in
/etc/protocols in Python
We have
socket.getprotobyname(NAME)
But there's no way to get the list of names
Any ideas if this is available in the stdlib somehwere ?
Thx

So as far as I understood what I should do is the following.
Go through my own XML keeping track of the full path of everything for
example
and so on, then for every entry found in this iteration, check the schema
to make sure that that particular construct is allowed
on that level of the tree

Any reason for that? Because the canonical answer to your question would be
lxml, which uses libxml2.

Could be a familiarity/ease issue as it was originally started by a
college student (and college students seldom have meaningful real
world experience) before it exploded in size. Also do not forget
that
The windows box is my development box, it's not where the script will be
