[Haskell-beginners] Review request

[C K Kashyap]

Hi,
I've written a small haskell program to extract a section from a file
between start and end markers. For example, if I have a file such as below
-
a
b
c
        <bug>
d
e
f
        </bug>
g
h
i

I'd like to extract the contents between <bug> and </bug> (including the
markers).

startTag = "<bug>"endTag = "</bug>"
process  = unlines . specialTakeWhile (f endTag) . dropWhile (f
startTag) . lines
        where f t x = not (x =~ t)
              specialTakeWhile :: (a -> Bool) -> [a] -> [a]
              specialTakeWhile ff [] = []
              specialTakeWhile ff (x:xs) = if ff x then
x:(specialTakeWhile ff xs) else [x]



It'll be great if I could get some feedback on this.


Regards,

Kashyap
