XML formatting help

Question

HI All,
I have a question. I have written a sample java program that will create an xml file. The program works properly, but the generated xml is not formatted. How can i format the xml file.
The java program code is
package com.spi.xml;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class WriteXML {
    static Document document;
        public static void buildDOM() {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            try {
              DocumentBuilder builder = factory.newDocumentBuilder();
              document = builder.newDocument();
              Element root = (Element) document.createElement("GUI");
              document.appendChild(root);
              Element curElement = document.createElement("Button");
              curElement.appendChild(document.createTextNode("Submit"));
              root.appendChild(curElement);
              curElement = document.createElement("Button");
              curElement.appendChild(document.createTextNode("Cancel"));
              root.appendChild(curElement);
              // Save the document to the disk file
                TransformerFactory tranFactory = TransformerFactory.newInstance();
                Transformer aTransformer = tranFactory.newTransformer();
                Source src = new DOMSource(document);
                Result dest = new StreamResult(new File("C:\\xmlFileName.xml"));
                aTransformer.transform(src, dest);
            } catch (Exception pce) {
                pce.printStackTrace();
        public static void main(String[] args) {
        buildDOM();
}The output (XML file)
<?xml version="1.0" encoding="UTF-8"?>
<GUI><Button>Submit</Button><Button>Cancel</Button></GUI>How can i format the xml file for multiple lines?

If you are using XML Schemas, you should check out
XML Beans -- you'll never (?) think about low-level
APIs again:
http://xmlbeans.apache.org/If you are not using XML Schemas, why not?We will be using the XML Schemas later. This is just a sample to write an xml file. The xml should be built dynamically.
