XML_Transformer: overloadNamespace help

Greetings,

    I'm having a little trouble understanding overloadNamespace in
    the XML_Transformer package.  Unfortunately, I dont seem to be good
    enough at reading source to decipher exactly what I can do with it,
    but what I wnat is something like this:


    <?php
        
    class Foo{

        var $data;

        funciton startElement($a, $b)
        {
            $this->data[$a]['attributes'] = $b;
        }

        function endElement($a, $b)
        {
            $this->data[$a]['cdata'] = $b;
        }

        function getData()
        {
            return $this->data;
        }
    }

    $t = new XML_Transformer();
    $foo = new Foo();

    $t->overloadElement('Foo', &$foo);

    $t->transform('<bar>some xml</bar>');

    var_dump($foo->getData());

    ?>


    Follow?

    Basically, I want the overloadNamespace object to be available for
    further tweaking after it is tranformed....

    Any help would be appriciated.

TIA,
 Tom
