Hi,
I have this basic question of how to print the character " without the backslash.
I'm trying to print html code, so i need " a lot.
giveHtml (Leaf (a,(b,c))) = ""
Can anybody give me a light here?
One way would be to define a helper function to write an opening tag given the tag name and a list of (var,value) pairs: tag :: String -> [(String,String)] -> String tag t ps = "<" ++ t ++ " " ++ concatMap (\(var, value) -> var ++ "=\"" ++ value ++ "\" ") ps ++ ">" then your code would become escape free: giveHtml (Leaf (a,(b,c))) = tag "frame" [ ("src", "") , ("name", [a]) , ("scrolling", "No") , ("noresize", "noresize") , ("id", [a]) , ("title", [a]) ] Regards, Brian. -- Logic empowers us and Love gives us purpose.
