I'm starting with 4DOM (which is compliant with an old version of level 2
HTML DOM, I just discovered) and some bits of pxdom (because 4DOM
deliberately doesn't do 'live' collections), plus various hacks applied by
me.  The code is currently not pretty, I must confess.  I expect I'll
discover soon how adequate this is for the task (the task being simply my
wanting a package for interpreting embedded JS that's relatively
dependency-free and as close to 'pure Python' as possible, not any
commercial interest)...

I won't use any rendering code.  This is for web scraping / testing.

Thanks!

Oh, sure, I understand that.  When I wrote 'just another thing...' I was
responding to your 'Plus XPCOM, of course' which, in its context,
suggested to me that you were partly selling its advantages as a pleasant
environment to work in (but of course, you were also referring to the fact
that "all" the Mozilla code is accessible through XPCOM, which is the
other great advantage).  As I said, though, PyXPCOM is nice, what I've
written is a hack.
