Which is not lxml.html.diff, I assume? (I'm not sure how HTML specific that
is, BTW). Also, for doctests, there is lxml.usedoctest that you can import
(the lxml web pages use it for doctests).

Not using the c14n interface (libxml2 doesn't support it). Serialising by hand
is not too hard, though. You can look at ElementTree._write() for an example:
