Subject: [PATCH] Selecting nodeIdentifiers by RegEx

Uses the nodeIdentifier as a regular expression to select matching nodes dynamically (e.g. <nodeIdentifier>worker-.*</nodeIdentifier>). Classic nodeIdentifiers without RegEx (like 'worker-1') are still possible.
This enables a dynamic node selection in cluster environments where nodes can be dynamically started or stopped. Previously all nodes had to be specified individually and produced an error if one was missing.
