DOMDocument::createCDATASection — Create new cdata node
This function creates a new instance of class DOMCDATASection. Dieser Knoten wird in Ihrem Dokument nicht sichtbar sein, bis dieser zum Beispiel mit der Funktion DOMNode->appendChild() eingefügt wird.
The content of the cdata.
The new DOMCDATASection or FALSE if an error occured.
If you would like to refer to the documentation for the class of the returned object, see http://www.php.net/manual/en/class.domcharacterdata.php
A common issue seems to be adding javascript to CDATA and the browser throwing a javascript error. To ensure the javascript works use the following code when adding CDATA:
<?php
/**
* Append Caracter Data to a node and check for a javascript node
*
* @param DOMElement $appendToNode
* @param string $text
*/
function appendCdata($appendToNode, $text)
{
if (strtolower($appendToNode->nodeName) == 'script') { // Javascript hack
$cm = $appendToNode->ownerDocument->createTextNode("\n//");
$ct = $appendToNode->ownerDocument->createCDATASection("\n" . $text . "\n//");
$appendToNode->appendChild($cm);
$appendToNode->appendChild($ct);
} else { // Normal CDATA node
$ct = $appendToNode->ownerDocument->createCDATASection($text);
$appendToNode->appendChild($ct);
}
}
?>
The result should be:
<script type="text/javascript">
//<![CDATA[
function someJsText() {
document.write('Some js with <a href="#">HTML</a> content');
}
//]]></script>
Here's a function that will create a CDATA-section around a string coming from SimpleXML.
<?php
function sxml_cdata($path, $string){
$dom = dom_import_simplexml($path);
$cdata = $dom->ownerDocument->createCDATASection($string);
$dom->appendChild($cdata);
}
?>
