@kroccamen While not that elegant, you can create a decorator to solve this 
issue. Here's a template to use:

    class MyDomElement extends DOMElement {
      function xpath($query) {
        return new 
DomNodeListDecorator($this->ownerDocument->getXpathSelector()-
>query($query, $this));
      }
    }

    class DomNodeListDecorator implements IteratorAggregate {
      protected $nodeList;

      function __construct($nodeList) {
        $this->nodeList = $nodeList;
      }

      function getIterator() {
        return $this->nodeList;
      }

      function __get($name) {
        if ($name == 'length') {
          return $this->nodeList->length;
        }
        throw new Exception("Undefined attribute {$name}");
      }

      function item($index) {
        return $this->nodeList->item($index);
      }
    }

I’d like to provide a valid use-case for this bug.

I have created an extended DOMDocument that upon __construct also creates an  
XPath object, that way I can add methods to DOMElement to allow for 
DOMElement->xpath ('...') instead of using DOMXPath->query ('...', DOMNode). 
This makes the DOM more chainable and simpler to use without so many temporary 
variables.

What I want to do is extend DOMNodeList so that one function call can apply to 
all nodes returned from an XPath query, e.g.

DOMNode->xpath ('a')->addClass ('link');

Is anybody aware of any other work around that can be used to achieve this same 
effect?

Any movement on this? The method should probably be called registerNodeListClass
