[db-wg] Query all route objects for a given AS?

Greetings, Sorry if this is an FAQ, but I'd like to know if there is a way to formulate a WHOIS query against whois.ripe.net in a way so as to obtain a complete list of the registered route objects that are associated with a given particular AS. If there's a way to do this, and if someone can instruct me on how it is done, I sure would appreciate that. Thanks.
