Hello Peter!
Lilypond can export to a format called "music streams", which is intended to
make the music representation easier for conversion programs. I reckon that
would be easier than the lilypond format itself. I don't have the link about
the music streams stuff, but if you search especially the devel list you'll
find some hints.

On the other hand, there is a commercial software that has some very outstanding
results in converting the pdf output from lilypond into Musicxml, among other
formats: PDFtoMusic. It does an amazing good job for lilypond scores. The
unregistered version allows you to save only the first page or a pdf of one
page. There´s no expiring date for the trial, and if you buy the product (199
USD) all the updates(upgrades) are free. The success of the conversion is that
it checks the font and vector information of the score. There's one version of
the software that works fine but musicxml export isn't included. But if you
have their notation program "Harmony Assistant" (70USD), then you could export
to musicxml from there.

Now, our musicxml really needs some improvement, it cannot even handle chords.
So it would be nice to find volunteers for that as well.

Regards,

Eduardo
