JSON Pointer

Simple implementation of the json-pointer spec:

http://tools.ietf.org/html/rfc6901

Usage

JSON pointer make it possible to retrieve arbitrary sub-objects from json objects.

>>> import json_pointer
>>> data = {'a': {'b': 'c'}, 'd': ['e', 'f', 'g']}

>>> json_pointer.Pointer('/a/b').get(data)
 'c'
>>> json_pointer.Pointer('/d/1').get(data)
'f'

It is also possible to set and unset data using pointers.

>>> data = {'a': {'b': 'c'}, 'd': ['e', 'f', 'g']}

>>> json_pointer.Pointer('/a/b').set('d')
>>> json_pointer.Pointer('/a/c').set('h')
>>> data
 {'a': {'d': 'c', 'c': 'h'}, 'd': ['e', 'f', 'g']}

>>> json_pointer.Pointer('/d/1').unset(data)
 {'a': {'d': 'c', 'c': 'h'}, 'd': ['f', 'g']}
