Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

public class CreateXML{
public static void createXmlFile(Document doc,String name,String address,String contactNo,String email) throws Exception {
        Element root = doc.createElement("Employee");
        doc.appendChild(root);
        Element element1 = doc.createElement("Emp_Name");
        root.appendChild(element1);
        Text text1 = doc.createTextNode(name);
        element1.appendChild(text1);

        Element element2 = doc.createElement("Emp_Address");
        root.appendChild(element2);
        Text text2 = doc.createTextNode(address);
        element2.appendChild(text2);

        Element element3 = doc.createElement("Emp_ContactNo");
        root.appendChild(element3);
        Text text3 = doc.createTextNode(contactNo);
        element3.appendChild(text3);

        Element element4 = doc.createElement("Email");
        root.appendChild(element4);
        Text text4 = doc.createTextNode(email);
        element4.appendChild(text4);

        TransformerFactory factory = TransformerFactory.newInstance();
        Transformer transformer = factory.newTransformer();
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");

        StringWriter sw = new StringWriter();
        StreamResult result = new StreamResult(sw);
        DOMSource source = new DOMSource(doc);
        transformer.transform(source, result);
        String xmlString = sw.toString();

        File file = new File("c:/employee.xml");
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file,true)));
        bw.write(xmlString);
        bw.flush();
        bw.close();
      }
      public static void main(String args[])throws Exception{
        DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = builderFactory.newDocumentBuilder();
        Document doc = docBuilder.newDocument();
        Scanner input=new Scanner(System.in);
        System.out.print("Enter Employee Name:");
        String name=input.nextLine();
        System.out.print("Enter Address:");
        String address=input.nextLine();
        System.out.print("Enter Contact No:");
        String contactNo=input.nextLine();
        System.out.print("Enter Email:");
        String email=input.nextLine();
        createXmlFile(doc,name,address,contactNo,email);
        System.out.println("Xml File is Created Successfully");
    }
}

Thanks
