can we get the max value of element from xpath

e.g: Xpath Query Expression: /Books/Book[@id='3'] to select XMLNode which id
is "3"

Can I use Xpath to get the MAX Book id?

Thanks in advanced.
 
use last() function like /Books/Book[@id=last()]

count is not the same as max :-)

That won't help unless the book ids are guaranteed to start at 1 and
increase by 1 each time.

The max() function sounds like what's required here.
