I've updated the parser here -
https://github.com/ckkashyap/LearningPrograms/blob/master/Haskell/Parsing/xm...
The whole thing is less than 100 lines and it can handle comments as well.
I have an outstanding question - What's the second parameter of the parse
function really for?
Regards,
Kashyap

Thank you so much ... I've updated my monad version here -
https://github.com/ckkashyap/LearningPrograms/blob/master/Haskell/Parsing/xm...https://github.com/ckkashyap/LearningPrograms/blob/master/Haskell/Parsing/xm...
and the Applicative version here - https://github.com/ckkashyap/LearningPrograms/blob/master/Haskell/Parsing/xm...
The applicative version however does not seem to work.
Is there a good tutorial that I can look up for Parsec - I am checking out http://legacy.cs.uu.nl/daan/download/parsec/parsec.html but I am looking for a tutorial where a complex parser would be built ground up.
Next I'd like to take care of escaped angular brackets.
Regards, Kashyap

if you disallow empty tags and "/" within tags, then you can avoid the notFollowedBy construct by:
openTag = try (char '<' *> many1 (noneOf "/>")) <* char '>'
C.
endTag :: String -> Parser String endTag str = string " string str <* char '>'
Well yes, modified to what Christian Maeder just suggested.
Cheers, Simon
