Java append new node to XML file

In this tutorial, you will learn how to append new node to xml file. Sometimes there is a need to append a new XML node to the xml file. Here is an xml file where we are going to append a new node.

file.xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<school>
<student>
<name>Angelina</name>
<address>Delhi</address>
</student>
<student>

import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

public class AppendNode {

public static void main(String[] args) {
try {
File xmlFile = new File("C:\\file.xml");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(xmlFile);
Element documentElement = document.getDocumentElement();
Element textNode = document.createElement("name");
textNode.setTextContent("Rose");
Element textNode1 = document.createElement("address");
textNode1.setTextContent("Delhi");
Element nodeElement = document.createElement("student");
nodeElement.appendChild(textNode);
nodeElement.appendChild(textNode1);
documentElement.appendChild(nodeElement);
document.replaceChild(documentElement, documentElement);
Transformer tFormer =
TransformerFactory.newInstance().newTransformer();
tFormer.setOutputProperty(OutputKeys.METHOD, "xml");
Source source = new DOMSource(document);
Result result = new StreamResult(xmlFile);
tFormer.transform(source, result);


} catch (Exception ex) {
