Oh dear, I feared someone would ask that.  OK, as long as you promise 
to remember that I wrote this in a hurry, you can find it here:

   http://svn.chezphil.org/libpbe/trunk/include/rxml.hh
   http://svn.chezphil.org/libpbe/trunk/src/rxml.cc

That currently says "GPL" but I could change that to Boost if people want.
