Limiting the number of AS's in an AS Path...

All,
If I wanted to filter out routes coming into a BGP peer to only routes
that had an AS Path of less than 10 in length, how would you recommend
doing it?

I am looking at creating some pretty elaborate regexp's like....

([0-9]*)?_([0-9]*)? (all the way out to 10 places)

But I'm thinking that there must be a feature or a more elegant way of
accomplishing this. Any thoughts?

As always, thanks in advance....
