    e540.  
    Adding a CDATA Section to a DOM Document</h3>

If `<code>]]&gt;</code>' appears in the CDATA section's text, the default XML
writers in J2SE 1.4 automatically break the CDATA section into two
CDATA sections; `<code>]]</code>' will appear at the end of the first section
while `<code>&gt;</code>' will appear at the beginning of the second section.


<pre>
    // Obtain an XML document; this method is implemented in
    // <a href="../javax.xml.parsers/BasicDom.html" class="eglink"><font size="-1"><b>e510</b> The Quintessential Program to Create a DOM Document from an XML File</font></a>
    Document doc = <font color="#0066ff"><i>parseXmlFile</i></font>(<font color="#0066ff"><i>"infilename.xml"</i></font>, <font color="#0066ff"><i>false</i></font>);
    
    // Add a CDATA section to the root element
    Element element = doc.getDocumentElement();
    CDATASection cdata = doc.createCDATASection(<font color="#0066ff"><i>"data"</i></font>);
    element.appendChild(cdata);
    
    // If "]]&gt;" appears in the text, two CDATA sections will be written out
    cdata = doc.createCDATASection(<font color="#0066ff"><i>"more]]&gt;data"</i></font>);
    element.appendChild(cdata);
</pre>
This is the sample input for the example:

<pre>
    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
    &lt;map&gt;
        &lt;entry key="key1" value="value1" /&gt;
        &lt;entry key="key2" /&gt;
    &lt;/map&gt;
</pre>
The resulting XML from running the example is:

<pre>
    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
    &lt;map&gt;
        &lt;entry key="key1" value="value1"/&gt;
        &lt;entry key="key2"/&gt;
    &lt;![CDATA[data]]&gt;&lt;![CDATA[more]]]]&gt;&lt;![CDATA[&gt;data]]&gt;&lt;/map&gt;
