Create a list from json file, with multiple values-CodePudding

I'm trying to get all the data from a json file however I have problems to filter out missing objects without one out of two values (EMAIL,JOB_TITLE).

Here's the json : [{"primary": "JOHN DOE", "attributes": [{"type": "double", "name":"BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "EMAIL", "value":"[email protected]"}, {"type": "string", "name": "JOB_TITLE", "value": "SALESMAN"} ], "aliases": [{"alias": "[email protected]"}]},{"primary": "LORRAINE DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": 456}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "STATUS", "value": "Unavaliable"}, {"type": "string", "name": "EMAIL", "value": "[email protected]"}, {"type": "string", "name": "JOB_TITLE", "value": "SECRETARY"} ], "aliases": [{"alias": "[email protected]"}, {"alias": "[email protected]"}]},{"primary": "JACK DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name":"JOB_TITLE", "value": "OWNER"}], "aliases": [{"alias":"[email protected]"},{"alias": "[email protected]"}]}, {"primary": "NOAH DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "EMAIL", "value": "[email protected]"}], "aliases": [{"alias": "[email protected]"}]}]

The list that I try to create:

"[email protected]": "SALESMAN",
"[email protected]": "SECRETARY"

The code that I used:

echo '[{"primary": "JOHN DOE", "attributes": [{"type": "double", "name":"BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "EMAIL", "value":"[email protected]"}, {"type": "string", "name": "JOB_TITLE", "value": "SALESMAN"} ], "aliases": [{"alias": "[email protected]"}]},{"primary": "LORRAINE DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": 456}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "STATUS", "value": "Unavaliable"}, {"type": "string", "name": "EMAIL", "value": "[email protected]"}, {"type": "string", "name": "JOB_TITLE", "value": "SECRETARY"} ], "aliases": [{"alias": "[email protected]"}, {"alias": "[email protected]"}]},{"primary": "JACK DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name":"JOB_TITLE", "value": "OWNER"}], "aliases": [{"alias":"[email protected]"},{"alias": "[email protected]"}]}, {"primary": "NOAH DOE", "attributes": [{"type": "double", "name": "BUILDING_NUMBER", "value": "123"}, {"type": "double", "name": "FLOOR", "value": 10}, {"type": "string", "name": "EMAIL", "value": "[email protected]"}], "aliases": [{"alias": "[email protected]"}]}]' | jq '.[].attributes[]|select(.name|contains("JOB_TITLE"), contains ("EMAIL"))' | jq .value | sed 'N;s/\n/:/' | sed 's/$/,/'

CodePudding user response：

This turns the attributes array into an object using from_entries, filters according to the presence of both keys using select and has, and extracts the values required using string interpolation:

jq -r '
  .[].attributes | from_entries
  | select(has("JOB_TITLE") and has("EMAIL"))
  | "\"\(.EMAIL)\": \"\(.JOB_TITLE)\""
'

"[email protected]": "SALESMAN"
"[email protected]": "SECRETARY"
