I've only tested one random MusicXML file, so I can't fully comment.
But it seems that musicxml2ly generates barchecks ("|") for every
measure. So you can simply use *these* to identify possible line breaks,
without actually going down the road of analyzing the content.
But my converted file actually *did* place one measure in a line, so I
don't see your problem. Could you please share some of that "messy"
LilyPond code?
