java - How to extract nested JSON Elements in Liferay -


i'm using liferay 6.2 , have jsonobject containing following:

{   "foo":{          "bar":{                 "baz":["42","23"]                }         } } 

i have string containing path/selector/whatsitcalled pointing somewhere in jsonobject: foo.bar.baz[0]

how go getting corresponding value jsonobject, i.e. "42"?

all methods find deal next level down, nothing seems cover nesting. parse path manually, isn't there easier way?

use java library perform xpath similar query json. i've used success in liferay.
