Examples of XQueryService

org.exist.xmldb.XQueryService
Execute XQuery expressions on the database. This interface is similar to {@link org.xmldb.api.modules.XPathQueryService}, but provides additional methods to compile an XQuery into an internal representation, which can be executed repeatedly. Since XQuery scripts can be very large, compiling an expression in advance can save a lot of time. @author Wolfgang Meier (wolfgang@exist-db.org)
