## Class XMLMultipleEventWriter

- java.lang.Object
- - org.apache.synapse.commons.staxon.core.util.EventWriterDelegate
  - - org.apache.synapse.commons.staxon.core.json.util.XMLMultipleEventWriter

- All Implemented Interfaces:
    XMLEventConsumer, XMLEventWriter

      public class XMLMultipleEventWriter
      extends EventWriterDelegate

  Simple delegate writer which generates `<?xml-multiple?>` processing instructions when writing a sequence of elements matching some element path. Use this class to trigger JSON array start events like this:

       XMLOutputFactory factory = new JsonXMLOutputFactory();
       XMLEventWriter writer = factory.createXMLEventWriter(...);
       writer = new XMLMultipleEventWriter(writer, false, "/alice/bob", ...);

    - #### XMLMultipleEventWriter

          public XMLMultipleEventWriter(XMLEventWriter parent,
                                        boolean matchRoot,
                                        String... multiplePaths)
                                 throws XMLStreamException

      Create instance.
      Parameters:
        `parent` - delegate
        `matchRoot` - whether the root element is included in paths
        `multiplePaths` - added via `addMultiplePath(String)`
      Throws:
        `XMLStreamException`

  - ### Method Detail

    - #### setParent

          public void setParent(XMLEventWriter parent)

      Overrides:

          public void addMultiplePath(String path)
                               throws XMLStreamException

      Add path to trigger `<?xml-multiple?>` PI. The path may start with `'/'` and contain local element names, separated by `'/'`, e.g `"/foo/bar"`, `"foo/bar"` or `"bar"`.
      Parameters:
