Description:
------------
A few E_NOTICE errors result when using the PDF format, and this may 
reveal other issues. Debugging is as follows:

Reproduce code:
---------------
Debugging simply added this to the notXPath() method definition:

  if ($depth == 0) {
    var_dump(array('tag' => $tag, 'stack' => $this->STACK));
  }

 The problematic line #88::

  if (isset($tag[$this->STACK[--$depth]])) {
