MusicXML for jazz rhythm section

Hi there,
I'm trying to see if I can find a bunch of musicXML scores that are written for jazz quartets but only the music rhythm section (bass, drum, piano chords) so I can playalong with them but take advantage of seeing the play head progress rather than using eyeballing which I'm not very good at right now. I'm looking for jazz standards right now.
I appreciate your comments.
Thanks.
Arya
