[Haskell-cafe] XMLParse module

[Huong Nguyen]

Hello all,

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,
