Re: [Haskell-cafe] xml packages

First question. As I saw in sources, both hxt and haxml uses [Char]'s. this is very inefficient. I want to know, does any effective parser for haskell, written in haskell, exists.

The TagSoup parser can generate ByteString syntax trees - but they're quite a bit slower than [Char] versions. I am planning to speed up the ByteString version in the future: http://code.google.com/p/ndmitchell/issues/detail?id=290

Efficient means using ByteString to store strings and possibly building representations that shares one string for all similiary named elements. If there is no, is anyone interested in writing one?

I intend to do that in TagSoup, and it can even be done now by running a Map state over the available strings with fmap. Thanks, Neil
