## Interface DOM3Serializer

- All Known Implementing Classes:
    DOM3SerializerImpl

      public interface DOM3Serializer

  This interface is not intended to be used by an end user, but rather by an XML parser that is implementing the DOM Level 3 Load and Save APIs.

  See the DOM Level 3 Load and Save interface at LSSeializer. For a list of configuration parameters for DOM Level 3 see DOMConfiguration. For additional configuration parameters available with the DOM Level 3 Load and Save API LSSerializer see LSerializer config.

  The following example uses a DOM3Serializer indirectly, through an an XML parser that uses this class as part of its implementation of the DOM Level 3 Load and Save APIs, and is the prefered way to serialize with DOM Level 3 APIs.

  Example:

          public class TestDOM3 {

          public static void main(String args[]) throws Exception {
              // Get document to serialize
              TestDOM3 test = new TestDOM3();

              // Serialize using standard DOM Level 3 Load/Save APIs
              System.out.println(test.testDOM3LS());
          }

          public org.w3c.dom.Document getDocument() throws Exception {
              // Create a simple DOM Document.
              javax.xml.parsers.DocumentBuilderFactory factory =
                  javax.xml.parsers.DocumentBuilderFactory.newInstance();
              javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();
              byte[] bytes = "".getBytes();
              java.io.InputStream is = new java.io.ByteArrayInputStream(bytes);
              org.w3c.dom.Document doc = builder.parse(is);
              return doc;
          }

          //
          // This method uses standard DOM Level 3 Load Save APIs:
          //   org.w3c.dom.bootstrap.DOMImplementationRegistry
          //   org.w3c.dom.ls.DOMImplementationLS
          //   org.w3c.dom.ls.DOMImplementationLS
          //   org.w3c.dom.ls.LSSerializer
          //   org.w3c.dom.DOMConfiguration
          //
          // The only thing non-standard in this method is the value set for the
          // name of the class implementing the DOM Level 3 Load Save APIs,
          // which in this case is:
          //   org.apache.xerces.dom.DOMImplementationSourceImpl
          //

          public String testDOM3LS() throws Exception {

              // Get a simple DOM Document that will be serialized.
              org.w3c.dom.Document docToSerialize = getDocument();

              // Get a factory (DOMImplementationLS) for creating a Load and Save object.
              org.w3c.dom.ls.DOMImplementationLS impl =
                  (org.w3c.dom.ls.DOMImplementationLS)
                  org.w3c.dom.bootstrap.DOMImplementationRegistry.newInstance().getDOMImplementation("LS");

              // Use the factory to create an object (LSSerializer) used to
              // write out or save the document.
              org.w3c.dom.ls.LSSerializer writer = impl.createLSSerializer();
              org.w3c.dom.DOMConfiguration config = writer.getDomConfig();
              config.setParameter("format-pretty-print", Boolean.TRUE);

              // Use the LSSerializer to write out or serialize the document to a String.
              String serializedXML = writer.writeToString(docToSerialize);
              return serializedXML;
          }

          }  // end of class TestDOM3
