First I thought to split the string on the " " but according to google Haskell do not have a split function.
Can I use pattern matching on some way ?
Instead of using Google, I suggest to first think about this in terms of types. You're looking for a function which can turn a string into a list of strings, i.e. String -> [String] You can feed types like this to Hoogle ( http://www.haskell.org/hoogle ) to get function which match that type. Searching for the above type signature yields some very relevant hits. :-) -- Frerich Raabe - raabe@froglogic.com www.froglogic.com - Multi-Platform GUI Testing
