Just TH and Happstack.Data's XML types. Its not complete or pretty, but it works for the XML files I have. I would love to try out and contribute to your library. I need to be able to specify names with different capitalisation (eg "UserName" in place of "userName" or "ABCData" in place of "abcData"). Currently I provide a list of names and use a function to convert them in TH to field names (so I get compiler errors if the field is not found). I also need some data to go in XML attributes. Currently I just read attributes as if they were elements, but it would be nice if it knew to write them as well. I also have something similar, but I did not use XmlPickler or Regular.

We'll probably soon release the generic pickler code so we can compare the efforts. Is your code on Hackage?

I didn't use the Regular package, just hand crafted TH. Perhaps we should combine efforts? Hi, I wrote a similar generic package to derive XmlPickler instances for types.

Our current system doesn't really need complex queries, but that might change in the future. Having type safe queries would indeed be a nice addition. Not yet.

Do you have a typed way to write the XQuery expressions as well? It would be nice to see that it matches the schema. Excellent! Do you have a typed way to write the XQuery expressions as well?
