note 86085 modified in function.simplexml-element-addChild by danbrown

I found this easy way to create a CDATA section as child value:

I extend the class SimpleXMLElement:

<?php
class SimpleXMLExtended extends SimpleXMLElement
{
  public function addCData($cdata_text)
  {
    $node= dom_import_simplexml($this);
    $no = $node->ownerDocument;
    $node->appendChild($no->createCDATASection($cdata_text));
  }
}
?>

Then in the main code:

<?php
$xml = new SimpleXMLExtended('<?xml version = "1.0" encoding = "UTF-8"?><root></root>');
$mynode = $xml->addChild("myname");
$mynode->addCData("my name contains everything I want &%<>");
echo $xml->asXml();
?>
