How to write to XML using java DOM API?

Hi,
This is a great forum with lots of bright developers' posts.
I hope I can get some useful hints from here since I couldn't catch anything by google.
My headache is that I don't know how to write some new items back to XML file which is parsed into a DOM tree using DOM API. For example, after a doc.createElement("elm")... how to save this new element to the XML file? I'm currently using java.
Thanks in advance.

Hi,
u can use following code but u need to download jar file for jdom from http://www.jdom.org/dist/binary/

import java.io.*;
import org.jdom.*;
import org.jdom.output.*;

public class CreateXML {

public static void main(String argv[]) {
Document document = createQuotesDocument();
outputDocument(document);
}

private static Document createQuotesDocument() {
// Create the root element and the document.
Element rootElement = new Element("quotes");
Document quoteDocument = new Document(rootElement);
rootElement.addContent(new Comment("All quotes that are fitted to show."));
Element quote = new Element("quote");
quote.addContent("You will meet a JDOM Guru today.");
quote.setAttribute(new Attribute("num", "1"));
Element author = new Element("author");
author.addContent("Software Objects");
quote.addContent(author);
rootElement.addContent(quote);
rootElement.addContent("I want to eat some ice cream.");
return quoteDocument;
} // createQuotesDocument

private static void outputDocument(Document document) {
try {
XMLOutputter outputter = new XMLOutputter(" ", true);
outputter.output(document, System.out);
} catch (java.io.IOException e) {
e.printStackTrace();
}
}//end of outputDocument

}//end of class


Thank You
