It would be interesting to have some more information about your intentions
here.

In general, the answer is no. It's a C extension which gets compiled
against the C-API of Python. You will quickly run into unresolved symbols
when you try using a binary module that was compiled against one Python
version in a different Python version.

However, it's built using exactly the same sources on all platforms, and
you only need to keep separate copies of the binary modules. The rest are
Python modules that are not platform specific. Also, the dependencies
(libxml2 and libxslt) do not depend on Python but only on the operating system.

Yes, although the API of HTMLParser is different from lxml's own HTML
parser and tree interface (which is basically trivial).

Thanks!
