--- Comment #2 from Anne <annevk@annevk.nl> ---
Okay, so basically this is the method that is desired:

Element.prototype.ancestor = function(selector) {
  var node = this
  while((node = node.parent) && node.nodeType == Node.ELEMENT_NODE)
    if(node.matches(selector))
      return node
  return null
}

Correct?
