public class XPathMessageSplitter
extends org.springframework.integration.splitter.AbstractMessageSplitter

Message Splitter that uses an XPathExpression to split a Document, File or String payload into a NodeList. The return value will be either Strings or Nodes depending on the received payload type. Additionally, node types will be converted to Documents if the 'createDocuments' property is set to true.
