Hi Michael,
If you just replace all 'str' with 'String' when reading the signature
then that will almost certainly be sufficient for your purposes. So
read it as:
fromAttrib :: String -> Tag String -> String
Where "Tag String" can be thought of as just "Tag". If you try to
parse HTML with regula
Ah thank you. I can go ahead and figure out how to parse that string.
Using a regex is tempting but I have a feeling I can get something
more maintainable if I use another approach.

When I see a code sample like this
main = do
posts <- liftM parseTags (readFile "posts.xml")
print $ head $ map (fromAttrib "Id") $
filter (~== (""))
posts
I have no idea how to match that up wit
