python-jsonpath-object-transform

Python implementation of https://github.com/dvdln/jsonpath-object-transform supporting the same language and API for transforming JSON documents using JSONPath.

>>> from jpot import *
>>> transform({"some":{"crazy":[{"foo": 1}, {"foo": 2}]}}, {"x":['$..crazy', {"a":'$.foo'}]})["x"]
[{'a': 1}, {'a': 2}]

Extensions over the javascript version

Multiple path expression engines

Support for path expressions using any of

• http://objectpath.org
• https://github.com/h2non/jsonpath-ng
• https://pypi.python.org/pypi/jsonpath

Chained transforms

Transforms for values returned by path expressions

>>> transform({"fie": {"gazonk": 47, "nana": 4}}, {"bar": {"$get": "$.fie", "$transform": {"blupp": "$.nana"}}})
{'bar': {'blupp': 4}}

Verbatim lists

A list wrapped inside another list [[]] produces a list as output, whose elements are the result of applying the elements of the list in the template to the data each at a time.

>>> from jpot import *
>>> transform({"foo": 47, "bar": 11}, {"my_synthesized": [["$.foo", "$.bar", {"gazonk": "$.foo"}]]})
{"my_synthesized": [47, 11, {"gazonk": 11}]}

Verbatim strings

>>> transform({"fie": 1}, {"foo": "Some text", "bar": {"$get": "$.fie"}}, verbatim_str=True)
{"foo": "Some text", "bar": 1}

Other verbatim values

>>> transform(something, {"foo": 47})
47
>>> transform(something, {"foo": true})
true
