Editing xml file with CDATA

I am editing the xml file using this code

$xml = simplexml_load_file($xmlfile) or die ("Unable to load XML file!"); 
$event->title = $newtitle;
$event->description = $newdescription;
file_put_contents($xmlfile, $xml->asXML());

I want to add a CDATA in description.I used this code

$event->description = '<![CDATA['.$newdescription.']]>';

But in xml the < and > are converted as &lt; and &gt;.How i can retain CDATA as it is .Is any other method for editing.Thanks in advance.

Actually i want to edit this xml file

<events date="06-11-2010">
    <event id="8">
      <title>Proin porttitor sollicitudin augue</title>
      <description><![CDATA[Lorem  nunc.]]></description>
    </event>
  </events>
  <events date="16-11-2010">
    <event id="4">
      <title>uis aliquam dapibus</title>
      <description><![CDATA[consequat vel, pulvinar.</createCDATASection></description>
    </event>
  <event id="1"><title>You can use HTML and CSS</title>
  <description><![CDATA[Lorem ipsum dolor sit amet]]></description></event></events>

With id

I think that you need to use DOM when your needs are more complex and no longer simple. There is a method createCDATASection.

Here's a basic example:

$dom=new DOMDocument();
$xml='data.xml';
$dom->load($xml);
$cdata=$dom->createCDATASection('<p>Foo</p>');
foreach ($dom->getElementsByTagName('item') as $item) {
    $item->getElementsByTagName('content')->item(0)->appendChild($cdata);
}

$dom->save($xml);

The XML that goes with this:

<?xml version="1.0" encoding="utf-8"?>
<data>
    <item>
        <title>Test</title>
        <content><![CDATA[<p>Foo</p>]]></content>
    </item>
</data>

With regards to your example and comment, the following should help you:

$dom=new DOMDocument();
$dom->validateOnParse = true;

$xml='data.xml';
$dom->load($xml);

// Unless the ID attribute is recognised
foreach ($dom->getElementsByTagName('event') as $event) { 
    $event->setIdAttribute('id', true);
}

$event = $dom->getElementById("1");
foreach ($event->getElementsByTagName('description') as $description) {
    $cdata=$dom->createCDATASection('<p>'. $description->nodeValue .'</p>');
    $description->replaceChild($cdata, $description->childNodes->item(0));
}

$dom->save($xml);

Essentially, SimpleXML will escape all values for XML use, so a lot of the reasons to use CDATA nodes aren't there. If you do need them however, it cannot be done in SimpleXML, use another alternative like DOMDocument and it's function createCDATASection()

Try

$xml = simplexml_load_file($xmlfile,'SimpleXMLElement', LIBXML_NOCDATA);

?
