Can you lay out some kind of plan for HaXml? (is 1.13.x now dead, is 1.19.x stable, ...?) This would help for new-ish projects like mine.

The 1.13.x stable branch sees minimal maintenance only, mostly to repair it to build after each new release of ghc breaks something.

Versions 1.14 - 1.19 (i.e. the darcs repo) introduce several API changes. I think those have now pretty-much stablised, but unfortunately the work to realise the benefit of those changes throughout the codebase is still incomplete in some places. That is why I have not frozen and released this branch as 2.0 yet.

For forward compatibility I would definitely recommend that a new project using HaXml should start with the 1.19 branch, not 1.13.

Thanks for your advice. Due to GHC 6.6.1 not being ByteString- upgradable, I have been slow in using the darcs version of HaXml. I am now using GHC 6.8.2 and so can try it out. My earlier-reported bug for the DTD parser stands: $ ~/bin/DtdToHaskell xhtml1-strict.dtd DtdToHaskell: In a sequence: in content spec of ELEMENT decl: head When looking for a non-empty sequence with separators: In a sequence: Expected % but found | in file xhtml1-strict.dtd at line 252 col 50 when looking for a content particle when looking for a content particle That is the XHTML 1.0 Strict DTD from the W3. Do you have any ideas what might have caused this? If not, I will have a poke around. It did work fine in 1.13.3, as I remarked earlier. cheers peter
