Re: [Haskell-cafe] XmlSerializer.deserialize?

Yes, or better: gshow' :: Data a => a -> String gshow' t = fromMaybe (showConstr(toConstr t)) (cast t) (which gets rid of the parentheses around numbers). Still doesnt get a deserialize though ;-) On 6/24/07, Andrea Vezzosi wrote:

As a side note i'd like to point out that introspectData has a problem with constructors containing Strings because show (x::String) /= x:

data Foo = Foo { bar :: String } deriving (Typeable,Data)

introspectData (Foo "quux") --> [("bar","\"quux\"")]

Those extras \" don't look very nice in the xml.. (the output of introspectData is also wrong in the article's example ) you should probably use a modified gshow:

gshow' :: Data a => a -> String gshow' x = fromMaybe (gshow x) (cast x)

which is id for Strings.
