Hi, I am trying to parse a .csv file and process the individual lines. Here is some code snippet (based on RWH Chapter 16 [1]): === test.hs === import Text.ParserCombinators.Parsec import System.Environment (getArgs) parseCSV :: String -> Either ParseError [[String]] parseCSV input = parse csvFile "(unknown)" input main = do do c <- getContents case parse csvFile "(stdin)" c of Left e -> do putStrLn "Error parsing input:" print e Right r -> mapM_ print r === END === Given an input file foo.csv: a,b,c d,e,f g,h,i and running the above test.hs using: $ runghc test.hs < foo.csv I get the following output: ["a,b,c"] ["d,e,f"] ["g,h,i"] Instead of using mapM_ print r, how can I obtain and pass each of the above lists (for example, ["a,b,c"]) to another function for processing? Appreciate any inputs, Thanks! SK [1] RWH. Using Parsec. http://book.realworldhaskell.org/read/using-parsec.html -- Shakthi Kannan http://www.shakthimaan.com
