Decode JSON with mochijson2 in Erlang

json erlang mochiweb mochijson2

I have a var that has some JSON data:

A = <<"{\"job\": {\"id\": \"1\"}}">>.

Using mochijson2, I decode the data:

 Struct = mochijson2:decode(A).

And now I have this:

{struct,[{<<"job">>,{struct,[{<<"id">>,<<"1">>}]}}]}

I am trying to read (for example), "job" or "id".

I tried using struct.get_value but it doesn't seem to work.

Any ideas?

The data is in {struct, proplist()} format, so here's what you do: 

{struct, JsonData} = Struct,
{struct, Job} = proplists:get_value(<<"job">>, JsonData),
Id = proplists:get_value(<<"id">>, Job),

You can read more about proplists at: http://www.erlang.org/doc/man/proplists.html
