one specific <a> or all <a> tags???
 But, you should be able to do:
 root.elements( "/a/d" ).size
 and that should return the count of ALL <d> elements under any <a> tag
 root.elements( "/a[1]/d" ).size
 should return the count of <d> elements under the first <a> tag ( it does
appear that the index operator in xpath is one-based not zero-based ).
 Hope that helps.
