yes, but since to do that you would have to parse not only the Denemo
xml but also the LilyPond syntax you would be doing more work than just
parsing the final LilyPond syntax that Denemo generates, so no one
would do that, it would not be profitable.

Generally, when people ask about MIDI playback I point them to the MIDI
that LilyPond generates (as heard in the View->Playback View) as it
handles more stuff than Denemo attempts. Have you checked if there is
an option to apply "swing" to the LilyPond MIDI - ask on their mailing
list.
But if it is *just* "swing" playback that you want - if Denemo's MIDI
is otherwise ok for you - then I think you could get there with a
little Denemo scripting.
For me to be able to help you do that I would need a much better
understanding of what you mean by swing playback. I'm guessing it means
lengthening (some?) some notes and shortening others in pairs? Perhaps
you could post Denemo scores of a few bars of music, one as normally
notated the other with the note durations altered so it plays back in
"swung" style?
