XML::DB::Service::XUpdateQueryService - provides XUpdate queries
$service = $collection->getService('XUpdateQueryService', '1.0'); $service->update($xupdate); $service->updateResource($xupdate, $documentId);
Implements XML::DB::Service, to provide XUpdate queries of the collection it is derived from.
In principle, an xupdate should just be sent over the transport mechanism to be dealt with by the database, if it supports XUpdate. Where a database doesnt support XUpdate natively yet, it has to be done by fetching the files, applying the update, and then writing them back.
Updates do not return a node count as per spec (what is this useful for anyway?), since that would require interfering with the guts of XML::XUpdate::LibXML, or reimplementing it.
