I think it would make sense to announce this on haskell-cafe@haskell.org too , which has a much broader readership. fegaras:
I would like to announce the release of HXQ: A Compiler from XQuery to Haskell.
HXQ is a fast and space-efficient translator from XQuery (the standard query language for XML) to embedded Haskell code. The translation is based on Haskell templates. HXQ takes full advantage of Haskell's lazy evaluation to keep in memory only those parts of XML data needed at each point of evaluation, thus performing stream-based evaluation. This results to an implementation that is as fast and space-efficient as any stream-based implementation based on SAX filters or finite state machines. Furthermore, the coding is far simpler and extensible since its based on XML trees, rather than SAX events. For example, an XQuery against the DBLP XML database (420MB) runs in 1.5 minutes.
