Querying json objects

jos

I’m looking for a way to query specific values from a json api response’s.
a bit xpath like query language.

I was thinking, transform the json to xml, run the xpath’s and return the results.

is there a suitable library out there?

There is RFC 6901 which defines JSON Pointer specification. With that term I have found something like that - GitHub - odogono/elixir-jsonpointer: Implementation of RFC 6901 JavaScript Object Notation Pointer strings in Elixir · GitHub.

I use jsn for json path queries:

% #{<<"user">> => #{<<"activated">> => true,
%                   <<"id">> => <<"123">>,
%                   <<"name">> => #{<<"first">> => <<"Jane">>,
%                                   <<"last">> => <<"Doe">>}}}

% get the user id
UserId = jsn:get('user.id', User).
% <<"123">>
