Java EE (Java Enterprise Edition) General Discussion

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();
    }

}




}

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Verb>
<Play EnglishTranslate="playing" />
</Verb>
