1. Set Up Your Environment: Ensure you have the Java Development Kit (JDK) installed and set up in your IDE (like Eclipse or IntelliJ IDEA). You will need to import the necessary XML libraries.
2. Create a Sample XML File: For demonstration, create a file named `students.xml` with the following content:```xmlJohnIndiaAlexRussiaRohanUSA```
3. Java Code to Read the XML File: Below is a simple Java program that reads the `students.xml` file and prints the student names and locations.```javaimport javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import org.w3c.dom.Document;import org.w3c.dom.Element;import org.w3c.dom.NodeList;import java.io.File;public class Main {public static void main(String[] args) {try {// Create a DocumentBuilderFactoryDocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();// Create a DocumentBuilderDocumentBuilder builder = factory.newDocumentBuilder();// Parse the XML fileDocument document = builder.parse(new File("students.xml"));document.getDocumentElement().normalize(); // Normalize the XML structure// Get all student elementsNodeList nList = document.getElementsByTagName("student");System.out.println("Students in the XML file:");// Loop through each student elementfor (int i = 0; i < nList.getLength(); i++) {Element student = (Element) nList.item(i);String name = student.getElementsByTagName("Name").item(0).getTextContent();String location = student.getElementsByTagName("location").item(0).getTextContent();System.out.println("Name: " + name + ", Location: " + location);}} catch (Exception e) {e.printStackTrace();}}}```

• DocumentBuilderFactory: This class is used to create a `DocumentBuilder` instance.
• DocumentBuilder: This instance is used to parse the XML file and create a DOM representation of the XML document.
• NodeList: This is used to retrieve a list of nodes (in this case, student elements) from the XML document.
• Element: Represents an element in the XML document, allowing you to access its attributes and child elements.

Using the DOM parser in Java is a straightforward way to read XML files. This method allows you to navigate through the XML structure and extract the necessary data easily. For larger XML files, consider using SAX or StAX parsers for better performance and lower memory usage.
