I'm having trouble parsing this. Is it ((recursive descent + qp_xml) vs.
old pyexpat) or (recursive descent vs.(  qp_xml + old pyexpat)).

PyExpat has mostly improved to add Unicode support.

PyExpat has the additional cost of having to cross the C->Python line
all of the time. Still, I haven't heard that anyone has made a
reasonably complete pure-Python parser that is as fast as PyExpat. I
don't know anything about Aaron's.
