Great!
So, what's different from http://ssax.sourceforge.net/? There is a version for Gambit somewhere, and I've been using it with Blackhole:

Right now I'm focusing on simple parsing, printing, and walking the
tree. But I think that going into the other areas (e.g. xpath) and
expanding the interface are very worthy goals. Having a fast, solid
XML library for Gambit is a good thing, even if it's based in C.

Another thing that would be nice to have is pure Scheme versions of
the libxml2 code, so that if you wanted not to deal with compiling
libxml2 you can just use only Scheme code. Sort of a pluggable backend
for the heavy lifting.

I haven't looked much at Black Hole but having support for it would
probably be good.

Thanks for your interest.
