For what purpose?  What would you hope to do with this information?

LilyPond's output is Postscript.  Postscript is a programming language;
it's certainly possible to interpret the Postscript to extract position
information.  However, that doesn't tell you anything about the notes. 
You could find out that there is a half-note glyph positioned at 4.25
inches across and 7.162 inches down, but what good would that do you?

LilyPond can also output MIDI.  If you are hoping to extract musical
meaning, that might be more useful.
