JsonSearch is a simple, yet effcient python library for searhing specific elements in json data.
>>> from jsonsearch import JsonSearch
>>> test_data = {
... "store": {
... "book": [
... {
... "category": "reference",
... "author": "Nigel Rees",
... "title": "Sayings of the Century",
... "price": 8.95
... },

... }
>>> jsondata = JsonSearch(object=test_data, mode='j')
>>> jsondata.search_all_value(key='title')
['Sayings of the Century', 'Sword of Honour', 'Moby Dick', 'The Lord of the Rings']
>>> jsondata.search_all_path(key='title')
[['store', 'book', 0, 'title'], ['store', 'book', 1, 'title'], ['store', 'book', 2, 'title'], ['store', 'book', 3, 'title']]
>>> jsondata.search_first_value(key='title')
'Sayings of the Century'
>>> jsondata.search_first_path(key='title')
['store', 'book', 0, 'title']
When json data have nested objects, JsonSearch allows you to find specific elements in json data easily.
Take the program above as an example, if you want to get the first 'title' value in data, you don't need to use test_data['store']['book'][0]['title'] anymore, you can just use jsondata.search_first_value(key='title').
JsonSearch is available on PyPI:
