jsonPath(obj, expr [, args])

parameters:

obj (object|array):

Object representing the JSON structure. expr (string): JSONPath expression string. args (object|undefined): Object controlling path evaluation and output. Currently only one member is supported. args.resultType ("VALUE"|"PATH"): causes the result to be either matching values (default) or normalized path expressions.

return value:

(array|false):

This example uses the toJSONString method from http://www.json.org/json.js . ``` JSONPath - Example (js)
