The code is so simple I'm not sure it even needs to go in the tagsoup
process stack (t@(TagOpen name attribs):rest) = process (stack:t) rest
process (TagOpen name1 _:stack) (TagClose name2:rest) | name1 == name2
= process stack rest
process stack rest = ... your code here ...
You are probably right that every application needs to tailor this
pattern to its own needs, but its sufficiently simple that I can't see
that being a problem.
