I am reading XMLParse module
http://www.germane-software.com/repositories/public/StatusReport/trunk/hxml-0.2/XMLParse.hs
But, I am not clear about the purpose of this module and the function of two functions:
parseInstance = unfoldr (pRun instanceItem) . pcdataMode
parseDTD = foldl (\a b->b a) emptyDTD . unfoldr (pRun dtdItem) . markupMode
parseDocument text =
case pRun prolog (pcdataMode text) of
Just (_, rest) -> unfoldr (pRun instanceItem) rest
Nothing -> [ErrorEvent "Error parsing prolog"] -- can't happen.
If any knows the meaning of those, please let me know.
Thanks a lot.
Best regards,
