comparing node types

Hi,

does anyone know a short expression that returns true if two nodes
($first1 and $first2) are of the same type?

What I currently have is 

   (($first1[self::text()] and $first2[self::text()]) or
    ($first1[self::comment()] and $first2[self::comment()]) or
    ($first1[self::processing-instruction()] and
             $first2[self::processing-instruction()] and
             name($first1)=name($first2)))

(element and attribute nodes omitted in this example ...)

Regards,
Oliver
