Export to MusicXML

[Alex Roitman]

Hello,

I apologize in advance if this was already asked and answered on this list.  
I’m looking into exporting some of my lilypond music into the MusicXML format. 
All I could find so far was the python-ly package that attempts to translate ly 
files into MusicXML.  It has some issues that could be fixed, and some that I 
don’t think could be so easily fixed, e.g. whether or not to place accidentals, 
beams, and so on.

It seems to me that the nature of the MusicXML format is such that in can only 
be correctly written when the music is interpreted in context.  Which is what 
lilypond does.  So I’m guessing that the right way to go about this is to 
create a new Translator, alongside Performer and Engraver, that instead of 
midi/graphical objects just dumps XML.

Finally, here are my questions:
1. Does this seem like a right approach?
2. Was this ever attempted and is there any work left that one can continue?

Thanks in advance for any help!
Alex
