You can write
__next__ = next
below the "next" method in both cases. No need to go through an indirection
here. I'd even reverse it: change the method definition to "__next__(self)"
and add a "next" alias instead of the above.
Also note that there is a Python package called "lxml" (developed by me)
that wraps libxml2 and libxslt. People tend to prefer it over the bare
Python bindings that come with both libraries.
