The crazy sed script below is my first attempt at a script that will convert as much HTML as possible to LaTeX. For my purposes I'm mostly interested in tables, lists, buttons, and comboboxes, but I included a few other things as well.
This is in an extremely experimental state, and is included here as
much for backup purposes and sharing as anything else.
Here's how you run the script on an HTML file named test.html:
sed -f html2latex.sed test.html > test.tex
That being said, here's the current source code for the html2latex.sed file:
#
# goal: to convert as much of an html document as possible to an
# equivalent sed script.
# i understand that, because of this approach, this can never be 100%
# accurate, but really what I'm after is the conversion of things
# like tables and lists.
# note that my html tags are pretty accurate here, but my latex tags
# leave some things to be desired.

Be warned, and good luck! ;)
