    Editing Text in a CDATA, Comment, and Text Node of a DOM Document</h3>

This example demonstrates all the available methods to get, set and modify
data in a CDATA, comment, or text node.


<pre>
    // Obtain a CDATA, comment, and text node
    Document doc = createDomDocument();
    CDATASection cdataNode = <font color="#0066ff"><i>doc.createCDATASection("")</i></font>;
    Comment commentNode = <font color="#0066ff"><i>doc.createComment("")</i></font>;
    Text textNode = <font color="#0066ff"><i>doc.createTextNode("")</i></font>;
    
    // All three types of nodes implement the CharacterData interface
    CharacterData cdata = cdataNode;
    cdata = commentNode;
    cdata = textNode;
    
    // Set the value of the node
    cdata.setData(<font color="#0066ff"><i>"some data"</i></font>);
    
    // Get the length of the text
    int len = cdata.getLength();    // 9
    
    // Get part of the text
    int offset = <font color="#0066ff"><i>5</i></font>;
    len = <font color="#0066ff"><i>4</i></font>;
    String s = cdata.substringData(offset, len); // data
    
    // Insert text
    offset = <font color="#0066ff"><i>5</i></font>;
    cdata.insertData(offset, <font color="#0066ff"><i>"more "</i></font>); // some more data
    
    // Append text
    cdata.appendData(<font color="#0066ff"><i>" please"</i></font>);       // some more data please
    
    // Delete text
    offset = <font color="#0066ff"><i>0</i></font>;
    len = <font color="#0066ff"><i>5</i></font>;
    cdata.deleteData(offset, len);              // more data please
    
    // Replace text
    String replacement = <font color="#0066ff"><i>"now"</i></font>;
    offset = <font color="#0066ff"><i>10</i></font>;
    len = <font color="#0066ff"><i>6</i></font>;
    cdata.replaceData(offset, len, replacement);// more data please
