Just what i was looking for, thanks.
Takes me back to the good old days, when i didn't just do engineering.

Regarding various people's references to ibm's xml diff -- unfortunately
they don't seem to give out code.
I can't believe someone would think there is a proprietary interest
in something like that, but there it is.
Maybe I should take out a patent on "An efficient difference algorithm
for structured textual markup". I bet I could get it through the PTO.
(If IBM didn't beat me to it, that is....)
