Hi friend,

Code to help in solving the problem :

import java.io.*;

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

public class XmlServlet{
public static void main(String args[]) throws IOException {

try
{
DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = builderFactory.newDocumentBuilder();
//creating a new instance of a DOM to build a DOM tree.
Document doc = docBuilder.newDocument();
new XmlServlet().createXmlTree(doc);

System.out.println("<b>Xml File Created Successfully</b>");
}
catch(Exception e)
{
System.out.println(e);
}

}

public void createXmlTree(Document doc) throws Exception {
//This method creates an element node
Element root = doc.createElement("Company");
//adding a node after the last child node of the specified node.
doc.appendChild(root);

Element child = doc.createElement("Location");
root.appendChild(child);

Element child1 = doc.createElement("Companyname");
child.appendChild(child1);

Text text = doc.createTextNode("Roseindia .Net");
child1.appendChild(text);

Comment comment = doc.createComment("Employee in roseindia");
child.appendChild(comment);

Element element = doc.createElement("Employee");
child.appendChild(element);

Text text1 = doc.createTextNode("Vineet Bansal");
element.appendChild(text1);

Element chilE = doc.createElement("Id");
chilE.setAttribute("name", "Vineet");
root.appendChild(chilE);

Text text12 = doc.createTextNode("status");
chilE.appendChild(text12);

//TransformerFactory instance is used to create Transformer objects.
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");

// create string from xml tree
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:/newxml.xml");
BufferedWriter bw = new BufferedWriter
(new OutputStreamWriter(new FileOutputStream(file)));
bw.write(xmlString);
bw.flush();
bw.close();

}
}
