Suuuuuuper old and are by and large unmaintained.  I've contacted the
old author 'cause I based some of my work off of it (worked as a
tutorial to libxml/libxslt for me, but has basically been rewritten).
The author said he had an itch and scratched it.

You bet!  I'm actually out to compete with AxKit here in a month or
two and think I can beat their performance #'s.  :~) I'm a perl->ruby
convert and want to offer something superior to Perl.  Other than an
way of dynamically creating pages via XML/XSLT, the Ruby bindings for
libxml/libxslt are also the basis for rubynet, Ruby's CPAN.


Here are the CVSweb repos for both libxml and libxslt:

http://cvsweb.rubynet.org/cgi-bin/cvsweb.cgi/projects/ruby-libxml/?cvsroot=rubynet

http://cvsweb.rubynet.org/cgi-bin/cvsweb.cgi/projects/ruby-libxslt/?cvsroot=rubynet


I've wrapped most of the data structures and have just finished
wrapping the parser contexts.  I'm about to go through and add parser
contexts to everything so that you can make multiple calls to xpath
w/o segv'ing the parser.  Speaking of, what's the best way to hook
into libxml's memory management given Ruby has its own garbage
collector that runs at uncontrollable times.  I was having some
problems cleaning up the xml parser in a persistent environment.  I
settled in on setting up a counter for how many XML documents were in
existence, but that seems really broken.  Any tips/incite there?  -sc
