I'm sing in a choir, and I'd like to offer members the opportunity to 
download pdfs and mp3s of both the whole song we're working on, or only 
one (or more) voice. Each voice is a staff, so I'd like to be able to 
list the names of the staffs, and remove all but one.

So, yes, as you suggested, I should be able to :
1) Edit the XML using standard xml tools
2) make it a .ly file using the lilypond script
3) make it a beautiful partition using lilypond :)

I thought I would use a python lib that would manage the MusicXML part 
for me, but in the end, MusicXML is just XML, so I'll be able to do it 
myself.

Thank you !
