RE: RE: Finding the lowest 'price' element

The XPath says: 

..locate the first Book element where the test [Price > other Book/Price] cannot be made true, for any other book. 

Sorry if that does not explain it well. The > represent ">" and ../ moves the XPath search up one parent.

cheers

"/Books/book[not(price > ../book/price)]/price"/
