[Haskell-cafe] TagSoup 0.9

[Neil Mitchell]

Hi Ralph,

My change notes have this being a change between 0.6 and 0.8. As
Malcolm says, any old uses of "Tag" should become "Tag String". The
reason is that Tag is now parameterised, and you can use Tag
ByteString etc. However, I should point out that Tag ByteString won't
be any faster than Tag String in this version (it's in the future work
pile).

Everyone's comments have been right. I previously included
Text.HTML.Download so that it was easy to test tagsoup against the
web. Since I first wrote that snippet the HTTP downloading libraries
have improved substantially, so people should use those in favour of
the version in tagsoup - you'll be able to connect to more websites in
more reliable ways, go through proxies etc. I don't intend to remove
the Download module any time soon, but I will do eventually.

Thanks, Neil
