Spring Integration ships with useful splitters that require no customization. One example is the splitter
provided to partition an XML payload along an XPath query, XPathMessageSplitter .
One example of a useful application of a splitter might be a text file with rows of data, each of
which must be processed. Your goal is to be able to submit each row to a service that will handle the
processing. What's required is a way to extract each row and forward each row as a new Message .
