Thanks. My initial post overstates the program a bit - what I actually
have is a cgi script which outputs my LIveJournal, which I then
server-side include in my home page (so my home page also displays the
latest X entries in my livejournal). The only html I need to convert
is the stuff that LJ spews out, which, while bad, isn't terrible, and
is fairly consistent. The stuff I need to convert is mostly stuff I
write myself in journal entries, so it doesn't have to be so
comprehensive that I'd need something like BeautifulSoup. I'm not
trying to parse it, just clean it up a little.
