Message-ID: <CAJp-NqwaSkR9VQRqrU0Q=ydunnxz+eqqm_stcdyyv8hqy+l...@mail.gmail.com> Content-Type: text/plain; charset="utf-8" Hi. I'm newbie to Haskell. I want to get date, it's type is [[String]]. The problem is that "the string that is used in regular expression pattern" is consumed. ie, disappear. Here is my code. ------------------------------------------------------------ import Text.Regex import Control.Applicative main :: IO() main = do myIn <- readFile "Data.dat" print $ lines <$> intoEachPt myIn intoEachPt :: String -> [String] intoEachPt = splitRegex (mkRegex "20[0-9]{13}AH021") ----------------------------------------------------------- How can I fix this? Data: ....there is many DIGIT.....201306000300001AH02112361640 9....... Output: [[....there is many DIGIT..."],["12361640 9......]....] I hope: [[....there is many DIGIT..."],["201306000300001AH02112361640 9......]....] -------------- next part -------------- An HTML attachment was scrubbed...
