Method Detail

runStage

public boolean runStage(EAIMessage eaiMessage)
                 throws PipelineStageException

Run PipelineStage logic.

The runStage() method expects an IXMLMessage with XML text as the payload.

runStage() extracts all <cd> elements from a 'cdcatalog' XML message and sets the MessagePipeline result as XML that contains a root element named 'totalPrice' with a value that is the sum the sum of all <price> elements.
