Mit SimpleXMLElement CDATA und Comment Sections erzeugen

Vor ein paar Tagen stellte sich mir bzw. stellte ich mir die Frage,
wie man mit SimpleXMLElement CDATA und Comment Sections erzeugen kann.

Kurz und gut, hier ist das Ergebnis in Form einer Klasse:

* @access public
*/
class XmlSimple {
/**
* creates new SimpleXML object with named root node
* @param string $sRoot name of root node
* @return object SimpleXMLElement
*/
public static function createRoot($sRoot) {
return simplexml_load_string('< ' . $sRoot . '/>', null, LIBXML_NOCDATA);
}
/**
* creates new SimpleXML object from XML string not ignoring CDATA
* @param string $sXml XML
* @return object SimpleXMLElement
*/
public static function fromString($sXml) {
return simplexml_load_string($sXml, null, LIBXML_NOCDATA);
}
/**
* creates new SimpleXML object from XML file not ignoring CDATA
* @param string $sXml XML file
* @return object SimpleXMLElement
*/
public static function fromFile($sFile) {
return simplexml_load_file($sFile, null, LIBXML_NOCDATA);
}
/**
* creates new SimpleXML object from XML URL not ignoring CDATA
* @param string $sUrl URL location
* @return object SimpleXMLElement
*/
public static function fromUrl($sUrl) {

}

*/
