I confess I just took the easy way out and installed all of Twisted (as
I've done with 4Suite mostly thus far in order to use the nifty 
Domlette :-)

I haven't browsed through the dependencies to see what of the other
Twisted pieces the microdom requires, so I can't say if it is extricable
from the wider framework.

One possibility I didn't try was to use tidy to generate real XHTML from
the crappy HTML.  It might then be posssible to use something more
common like the minidom implementation to navigate the HTML.

For me, extracting data from malformed but consistent HTML is a 
necessary task, so I do sometimes have to make some compromises
in my selection and use of tools.
