Attributes and count() in xpath expression

Question

Given the following XML file :

    
        3
        
    
    

        

Answer 1

/*/*/*

This selects all "grand-children of the top element -- these are: c, d, c, d

/*//*

This selects all descendant elements of the top element: b, c, d, b, c, d, e, f

/*/*//@*

This selects all attributes either of children of the top element or of their descendants: n, o, p, n, o, p, q, r, s.

Therefore, the counts produced must be, respectively:

4, 8, 9

XSLT - based verification:

 

 
   
=========
   
=========
   
 

When this transformation is performed on the provided XML document (never, never ever present the document with a picture!!!):

 
   3
   
 
 
   3
   
     2
   
 
 

The Xpath expressions are evaluated and their results are copied to the output:

   4
=========
   8
=========
   9
