Hi,

I have installed cabal and HaxMl

cabal install HaXml

but my .hs file cannot find

import Text.XML.HaXml.Xml2Haskell (readXml)

giving

*** Chasing dependencies: Chasing modules from: *ch.hs

ch.hs:3:8:     Could not find module `Text.XML.HaXml.Xml2Haskell':       locations searched:         Text/XML/HaXml/Xml2Haskell.hs         Text/XML/HaXml/Xml2Haskell.lhs

It would seem only to be looking in the current directory.

Hoping I have just missed something obvious.

In a way.

Text.XML.HaXml.Xml2Haskell was in HaXml-1.13, but is no longer in HaXml since version 1.19 (current is 1.22.5). Old tutorial, I guess.

There are two functions with the name readXml in the new versions, in Text.XML.HaXml.XmlContent and Text.XML.HaXml.XmlContent.Haskell (probably the same function, just exported from both modules).

The type has changed, instead of XmlContent a => String -> Maybe a, it is now XmlContent a => String -> Either String a, presumably specifying the parse failure now if there is one, otherwise I expect the behaviour to be the same.

I am trying to use XsdToHaskell but am getting stuck. The page http://projects.haskell.org/HaXml/ has dead links for DtdToHaskell and XsdToHaskell There is an apparently dead project at http://code.google.com/p/xsdtohaskell/ I have a set of .xsd file which reference each other and the command XsdToHaskell chassis.xsd > Chassis.xsd.hs generates a lot of haskell, but seems to include debugging eg Parse Success! Do you or others know of some uptodate documentation? cheers Tim -- Tim Pizey http://pizey.net/~timp
