Extending Element class in a dom tree?

[Erik Franzén <erik@xxxxxxxxxxxxxx>]

The DOM implementation i PHP5 allows classes to be extended. Extending 
the Document class is no problem, but how can I extend the Element class 
and use it in a DOM tree?

DOMDocument::createElement returns a DOMElement object which you cannot 
extend.

Could this be a solution?

class MyElement extends DomElement {
    function __construct($a_stTagName) {
        //has to be called!
        parent::__construct($a_stTagName);
    }

    function myFunction() {
	// do something
    }
}

$oDom = new DomDocument();
$oMyElement = new MyElement('mytag');

$oMyElement = $oDom->importNode($oMyElement, true);
$oMyElement = $oDom->appendChild($oMyElement);
