Author: ips
Date: Wed May 4 11:57:29 2005
New Revision: 168166
URL: http://svn.apache.org/viewcvs?rev=168166&view=rev
Log:
added support to query expression evaluator interface for querying against an
arbitrary context (i.e. a DOM Node or an XmlObject); we will be able to
leverage this for WSN subscription selectors which are query expressions that
are evaluated against notif messages
