By "stream," they really just mean a "file object," of which sys.stdin
is an example.  You're passing in a filename, which isn't the same
thing.  Instead, all you need to do is create a file with it:

	FromXmlStream(file(sys.stdin))

or

	FromXmlStream(open(sys.stdin))

for older versions of Python.
