Hi friend,

Code to help in solving the problem :

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

public class CreatXMLFile {
public static void main(String[] args) throws Exception {
BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter number to add elements in your XML file: ");
String str = bf.readLine();
int no = Integer.parseInt(str);
System.out.print("Enter root: ");
String root = bf.readLine();
DocumentBuilderFactory documentBuilderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder =
documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement(root);
document.appendChild(rootElement);
for (int i = 1; i <= no; i++){
System.out.print("Enter the element: ");
String element = bf.readLine();
System.out.print("Enter the data: ");
String data = bf.readLine();
Element em = document.createElement(element);
em.appendChild(document.createTextNode(data));
rootElement.appendChild(em);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
}
}

Thanks
