Malcolm, Thanks. I finally got Graham's version to build by: ./configure and then using the following Setup.hs and HaXml.cabal files. I haven't tried with Hugs or nhc. I had to modify a few bits of code on the way (e.g. changing parseUriReference to parseURIReference) but I assume that these will be fixed by the fact you are merging the two versions? Otherwise let me know and I will attempt to provide patches. Dominic. PS I may to expose a few more modules as I go along.
