    To convert dom to a string try the code:

    DocumentBuilderFactory domFact = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = domFact.newDocumentBuilder();
    Document doc = builder.parse(st);
    DOMSource domSource = new DOMSource(doc);
    StringWriter writer = new StringWriter();
    StreamResult result = new StreamResult(writer);
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    transformer.transform(domSource, result);
    System.out.println("XML IN String format is: \n" + writer.toString());

    Try this code:

    import java.io.*;
    import javax.xml.transform.*;
    import javax.xml.transform.dom.*;
    import javax.xml.transform.stream.*;
     
    //method to convert Document to String
    public String getStringFromDocument(Document doc)
    {
       try
       {
          DOMSource domSource = new DOMSource(doc);
          StringWriter writer = new StringWriter();
          StreamResult result = new StreamResult(writer);
          TransformerFactory tf = TransformerFactory.newInstance();
          Transformer transformer = tf.newTransformer();
          transformer.transform(domSource, result);
          return writer.toString();
       }
       catch(TransformerException ex)
       {
          ex.printStackTrace();
          return null;
       }
    }

    Converting dom to string follow these codes:

    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer trans = tf.newTransformer();
    StringWriter sw = new StringWriter();
    trans.transform(new DOMSource(document), new StreamResult(sw));
    return sw.toString();
