Splitting XML messages

XML is one of the most frequently split payload types. This recipe will show how you can use Camel's support for implicit type conversion, and XPath support, to process XML fragments individually.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.splitjoin.splitxml package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with splitXml.

      <author>Scott Cranton</author>
      <author>Jakub Korab</author>
    </authors>
  </book>
  <book category="Cooking" title="Camel Cookbook">
    <authors>
      <author>Heston Ramsey</author>
      <author>Gordon Blumenthal</author>
