here try input in textbox city name if match on xml file return me there country name.
dont error not getting result.
think problem in xpath pleasae me out of this.

use:

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

an equivalent expression is:

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