[xmlblaster] implementing query in addition to publish / subscribe

[Michael Atighetchi <matighet at bbn.com>]

How difficult would it be to enhance xmlblaster to deal with query
operations in addition to publish & subscribe ?

The query operation would be very similar (ie allow xpath
and regex matching) to a time-limited subscribe operation that only
returns the current set of messages known to xmlblaster and the
terminates.

It could probably be implemented using direct JDBC calls, however, I
would prefer an implementation that goes through xmlblaster utilizing
the parsed messages in the DOM.

Anyone has ideas about how to best approach this ?
