Sorry, I am not clear at some point in your answer:

1) The function lex :: String -> [(String,String)] and filter :: (a -> Bool) -> [a] -> [a] So, I did not see how filter can use the list of tuple string of lex.

You can write a function lexList, of type String -> [String], by repeatedly calling lex - its not too hard. Once you have this the filter will work. Thanks Neil
