How can CDATA sections be added to XML files generated using SimpleXmlElement?

Creating CDATA Using SimpleXmlElement

When generating XML files, it's often necessary to include CDATA sections. While SimpleXmlElement doesn't natively support creating CDATA, a customized version can be used to achieve this functionality.

Customizing SimpleXmlElement

The following code defines a SimpleXMLExtended class that extends SimpleXmlElement and provides a custom addCData function:

<code class="php">class SimpleXMLExtended extends SimpleXMLElement {
    public function addCData( $cdata_text ) {
        $node = dom_import_simplexml( $this );
        $ownerDocumentNode = $node->ownerDocument;
        $node->appendChild( $ownerDocumentNode->createCDATASection( $cdata_text ));
    }
}</code>

Creating XML with CDATA

To create an XML file with CDATA, follow these steps:

1. Create a SimpleXMLExtended object representing the desired XML structure.
2. Use the addCData function to insert CDATA into a node.
3. Add attributes to nodes as needed.
4. Save the XML file using saveXML.

Example

The following code demonstrates the creation of an XML file with a CDATA section:

<code class="php">// Create SimpleXMLExtended object
$xml = new SimpleXMLExtended('<site/>');

// Insert CDATA into title node</code>
