How to build xml CDATA sections?

This example demonstrate how to add CDATA section into an xml document. A CDATA section indicates a block that shouldn't be parsed. To build a CDATA section just wrap the string with a CDATA object.

package com.javacoderanch.example.jdom;

import org.jdom.input.SAXBuilder;
import org.jdom.Document;
import org.jdom.JDOMException;
import org.jdom.Element;
import org.jdom.CDATA;
import org.jdom.output.XMLOutputter;
import org.jdom.output.Format;


public class JDOMBuildCDATASection {
    public static void main(String[] args) {
        String xml =
                "<root>" +
                "   <comments>" +
                "       <comment></comment>" +
                "   </comments>" +

        SAXBuilder builder = new SAXBuilder();
        try {
            Document document = StringReader(xml));
            Element root = document.getRootElement();
            Element comments = root.getChild("comments");

            Element comment = comments.getChild("comment");

            // Using the setContent and addContent to add CDATA section into
            // the xml element.
            comment.setContent(new CDATA("<b>This is a bold string</b>."));
            comment.addContent(new CDATA("<i>And this an italic string</i>."));

            XMLOutputter outputter = new XMLOutputter(Format.getPrettyFormat());
            outputter.output(document, System.out);

            // Reading a CDATA section is simply done by calling the getText
            // method. It doesn't care if it was a simple string or a CDATA
            // section, it will just return the content as string.
            String text = comment.getText();
            System.out.println("Text = " + text);
        } catch (JDOMException e) {
        } catch (IOException e) {
