How to Embed CDATA Sections into XML Using an Extended SimpleXmlElement Class?

How to Incorporate CDATA into an XML File Using SimpleXmlElement

Issue Description

SimpleXmlElement provides a convenient method for creating and modifying XML documents. However, it lacks the straightforward functionality to embed CDATA sections into the XML output. The challenge lies in adding CDATA sections within the XML elements to enhance their content.

Solution

An extended version of the SimpleXmlElement class, christened SimpleXMLExtended, offers an elegant solution to this conundrum. By leveraging this custom class, you can effortlessly inject CDATA sections into your XML structures.

Implementation

The following code snippet exemplifies how to use the extended class:

<code class="php">// Customized 'SimpleXMLElement' class.
class SimpleXMLExtended extends SimpleXMLElement {

  // Create CDATA section custom function.
  public function addCData( $cdata_text ) {
    $node = dom_import_simplexml( $this ); 
    $ownerDocumentNode = $node->ownerDocument;

    $node->appendChild( $ownerDocumentNode->createCDATASection( $cdata_text )); 
  }

}

// Name of the XML file.
$xmlFile = 'config.xml';

// <?xml version="1.0"?>
// <site></site>
$xml = new SimpleXMLExtended( '<site/>' );

// Insert '<title></title>' into '<site></site>'.
$xml->title = NULL; // Essential to have a node for appending.

// CDATA section custom function.</code>
