> xpe.evaluate("/", document.body ... // returns window.document in Webkit.

The description doesn't match test case - in the latter, it's a detached
subtree of elements created with document.createElement:


  var fset = window.fset = document.createElement('fieldset');
  fset.appendChild( document.createElement('legend') );
  var form = document.createElement('form');
  form.appendChild( document.createElement('input') );
  fset.appendChild( form );

  // get fieldset
  assert( evaluateXPath(fset,'/')[0] == fset, 'Trying to get fieldset element.'
); // fails for webkit
  assert( evaluateXPath(fset,'/form')[0] == form, 'Tring to get form element'
);


Anyway, the XPath spec <http://www.w3.org/TR/xpath/> says "/ selects the
document root (which is always the parent of the document element)". Why do you
think that this is a bug in WebKit?
