How to write CDATA using SimpleXmlElement?

Question

I have this code to create and update xml file:

\');
$xml->title          


        

Answer 1

Here's my version of this class that has a quick addChildWithCDATA method, based on your answer:

    Class SimpleXMLElementExtended extends SimpleXMLElement {

  /**
   * Adds a child with $value inside CDATA
   * @param unknown $name
   * @param unknown $value
   */
  public function addChildWithCDATA($name, $value = NULL) {
    $new_child = $this->addChild($name);

    if ($new_child !== NULL) {
      $node = dom_import_simplexml($new_child);
      $no   = $node->ownerDocument;
      $node->appendChild($no->createCDATASection($value));
    }

    return $new_child;
  }
}

Simply use it like that:

$node = new SimpleXMLElementExtended();
$node->addChildWithCDATA('title', 'Text that can contain any unsafe XML charachters like & and <>');
