A good understatement ;-)

I found all that, split over two sites:


Those interested in the XML parser, SSAX, should go straight for


which is the paper describing its design and use. It's typical
research code: a lot of attention is given to the overall design and
to the data structures and algorithms used in the implementation, but
there's almost no documentation for users, nor anything one could call
software distribution or maintenance. It doesn't look like something
one would want to have as a dependency in a package meant for
production use.

Ah, now I understand what the xexp stuff is all about :-)

But I still wonder what someone in my situation should do. It looks
like SSAX does all I need, and well. But with all those
similar-but-not-quite-the-same packagings, how to pick the one most
likely to be available and working a few years from now?
