     *   whole logical text node as seen by XPath, unless the node is empty
     *   in which case it may not serve as the XPath context.
     * @param type If a specific <code>type</code> is specified, then the

     *   object which may be reused and returned by this method. If this is
     *   specified as <code>null</code>or the implementation does not reuse
     *   the specified result, a new result object will be constructed and
     *   returned.For XPath 1.0 results, this object will be of type
     *   <code>XPathResult</code>.

     *   1.0 results, this object will be of type <code>XPathResult</code>.
