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);
