"I see says the blind man, as he picked up his hammer and saw" Thanks David! -----Original Message----- From: David Carlisle [mailto:davidc@xxxxxxxxx] Sent: Friday, January 07, 2005 11:18 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Predicates > Could someone please explain to me the difference between: No. (There is no difference in this case) the difference between players[position()=2 and position()=2] and players[position()=2 ][ position()=2] and is that the first one selects the set of players for which position is 2 and 2 so it's the same as players[2] the second one selects all teh players for which poistion is 2 and then selects _from this list_ the player with position 2 (which won't exist as there will be at most one player with position 2 selected by the first filter. ie it's player[2][2] which is empty. converseley player[2][1] is the same as player[2] but player[position()=2 and position()=1] is empty.
