I think this may be the sort of problem Guido was pointing to this weekend.
My guess is that you specified "c:\foo\bar.xml" as for parsing, and the
software checked and saw that that file did not exist, and then tried to
interpret it as a URL.
So as usual, it seems the BDFL is right, but not for the reasons he originally
So can we think of a better algorithm than the current "check for file, and if
it doesn't exist, just blindly toss it to urllib)?
I personally think it's more important to be able to interpret things as URL
than to interpret things as a file-name.
Maybe a flag named "force_file_interpretation" or the like is in order.
This problem affects 4Suite as well.
