2 You apparently replaced your question with something pletely different after someone tried answering it. Why not just start a new question? – Barmar Commented Apr 21, 2013 at 6:03
I pletely agree with @Barmar. It is not remendable to pletely change the question just on the day before the deadline. Please, ask a new question, if you have a new problem. – Dimitre Novatchev Commented Apr 26, 2013 at 4:30

Use:

var xPath = '//*[@value = "' + city + '"]/../../@value';

An equivalent expression is:

var xPath = '//*[*/*[@value = "' + city +  ']]/@value';

As far as I remember, lists don't work like that... they're variables associated with a given value, so it's more like:

list($a, $b, $c) = [1, 2, 3];

Anyway, why don't you take a look at the 'Lists' section in the phpredis page? It's one of the remended PHP clients for Redis, and its examples are quite clear
