How to write CDATA using SimpleXmlElement

0 votes

I have this code to create and update xml file:

<?php
$xmlFile    = 'config.xml';
$xml        = new SimpleXmlElement('<site/>');
$xml->title = 'Site Title';
$xml->title->addAttribute('lang', 'en');
$xml->saveXML($xmlFile);
?>

This generates the following xml file:

<?xml version="1.0"?>
<site>
  <title lang="en">Site Title</title>
</site>

The question is: is there a way to add CDATA with this method/technique to create xml code below?

<?xml version="1.0"?>
<site>
  <title lang="en"><![CDATA[Site Title]]></title>
</site>

Hello @kartik,

Try this:

class MySimpleXMLElement extends SimpleXMLElement{

        public function addChildWithCData($name , $value) {
            $new = parent::addChild($name);
            $base = dom_import_simplexml($new);
            $docOwner = $base->ownerDocument;
            $base->appendChild($docOwner->createCDATASection($value));
        }

    }

        $simpleXmlElemntObj = new MySimpleXMLElement('<site/>');

        /* USAGE */

        /* Standard */
        $simpleXmlElemntObj->addChild('Postcode','1111');

       /* With CDATA */
       $simpleXmlElemntObj->addChildWithCData('State','Processing');


    /* RESULT */
    /*
    <?xml version="1.0"?>
    <site>
        <Postcode>1111</Postcode>
        <State><![CDATA[Processing]]></State>
    </site>
   */

Hope it works!!
