e540. Adding a CDATA Section to a DOM Document

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

    // Obtain an XML document; this method is implemented in
    // e510 The Quintessential Program to Create a DOM Document from an XML File
    Document doc = parseXmlFile("infilename.xml", false);
    
    // Add a CDATA section to the root element
    Element element = doc.getDocumentElement();
    CDATASection cdata = doc.createCDATASection("data");
    element.appendChild(cdata);
    
    // If "]]>" appears in the text, two CDATA sections will be written out
    cdata = doc.createCDATASection("more]]>data");
    element.appendChild(cdata);

This is the sample input for the example:

    <?xml version="1.0" encoding="UTF-8"?>
    <map>
        <entry key="key1" value="value1" />
        <entry key="key2" />
    </map>

The resulting XML from running the example is:

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