extracting xml tag name

hi,

how can i get the NAME of the XML node,
example -
SELECT EXTRACT (VALUE (e), '/').getstringval () as xml

     , EXTRACTVALUE (VALUE (e), '/') as VALUE
     --, ??? as tag
  FROM TABLE (XMLSEQUENCE (EXTRACT (
       XMLTYPE ('<A>
                    <B>2</B>
                    <C>3</C>
                    <D>4</D>
                </A>'
            ), '/A/*'))) e

the result should be - (the first & second are ok, but how to get the third ?) -

xml

---


<B>2</B>

<C>3</C>

<D>4</D> 


value 
----- 
2 
3 
4 

tag 
--- 
B 
C 
D 

Thanks, 
Shay
