How I can append new node in existing XML file

Question

I've just begun learning DOM XML , so I'm currently at a very beginner level.
I have an existing XML file that I would like to add an additional node to before saving it to another variable.
how I can append new node in this file.
now this code is overwrite new data over old data
The code looks like this:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Attr;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class VerbXMLWriter
    static String EVerb3;
    static String englishTranslate3;
    public void VerbXMLWriter(String EVerb, String englishTranslate )
         EVerb3 = EVerb;
         englishTranslate3=englishTranslate;
    File xmlFile = new File("VerbDB.xml");
    DocumentBuilderFactory factory =  DocumentBuilderFactory.newInstance();
    try
     DocumentBuilder builder = factory.newDocumentBuilder();
     Document document = builder.newDocument();
    Element root = document.createElement("Verb");
     document.appendChild(root);
     Element verb = document.createElement(EVerb3);
     verb.setAttribute("EnglishTranslate",englishTranslate3);
     root.appendChild(verb);
     Source xmlSource = new DOMSource( document );
     Result result = new StreamResult( new FileOutputStream(xmlFile) );
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer =
    transformerFactory.newTransformer();
    transformer.setOutputProperty( "indent", "yes" );
     transformer.transform( xmlSource, result );
  catch(TransformerFactoryConfigurationError factoryError )
    factoryError.printStackTrace();
   catch (ParserConfigurationException pc)
       pc.printStackTrace();
   catch (IOException io)
      io.printStackTrace();
   catch(Exception excep )
       excep.printStackTrace();

</Verb>Edited by: itb402 on Mar 9, 2008 6:05 AM

Answer 1

in your code you are already appending new nodes to the root node. so what exactly is your problem? The following steps are usually taken for appending a new node:
1. Read the XML document
2. Build a DOM tree
3. Navigate to the node under which you want to insert the new node
4. Create a new node.
5. Insert the new node to the node selected in point #3.
