Does exist a bridge for saxon8.jar?

i’d like to use saxonb8-9j mostly saxon8.jar from Ruby (not from jRuby)
for XSLT 2 and XPATH 2 and i wonder if someone wrote a bridge for that
jar ?

otherwise would it be difficult to build a gem for that purpose ?

or the “best” way would be to use ‘yajb/jbridge’ ?
