I meant attribute() - attribute() and attributes() are quite different
things ;)

You can use "elements()" (and "attributes()") to avoid getting the
error, i.e.
trace("Full games: " + games.game.(elements("user").length() ==
3).length());

Hello fellow flashcoders,
I'm still struggling with my e4x problem. With Kenneth's
help I've got it partly working for the cases
where each game has at least 1 user node:
var games:XML =
<games>
<game>
<user/>
<user/>
<user/>
</game>
<game>
<user/>
<user/>
</game>
<game>
<user/>
<user/>
</game>
</games>;
trace("All games: " + games.game.length());
trace("Full games: " + games.game.user.(length() == 3).length());
trace("Vacant games: " + games.game.user.(length()< 3).length());
This works well. But once I have a game with no user's,
i.e.<game></game> or just<game/> it fails with runtime error:
ReferenceError: Error #1065: Variable user is not defined.
I know, that when using e4x you're first supposed to test
for a game.user.length()!=0 before referencing a user node.
But how do you do it in this case, when I'm trying to count total
numbers?
Thank you
Alex
