Well, I've long since forgotten awk and sed (time for a Francis rant?),
but you can do this with a Perl oneliner:

perl -pi.bak -e 's!<a href="http://some.url/([^"]*)">!<a href="./$1">!g' *.html

This (should... I haven't tested it to make sure) do what you want, with
the added bonus of saving all modified files as <whatever>.html.bak in
case something nasty happens.
