Selecting entries of a sub array

I have json that looks like:

"base": "abc", "members" : [ "fn": "maurice", "ln": "hickey", "fn": "john", "ln": "smith", "fn": "robin", "ln": "smith", ... ], "date": "2018-08-26"

I am trying to write a jq filter to give me the same schema output but with only a subset of the members array e.g. all the "smith"s

"base": "abc", "members" : [ "fn": "john", "ln": "smith", "fn": "robin", "ln": "smith" ], "date": "2018-08-26"

Any pointers would be appreciated.

Are you specifically looking for a jquery filter or can you use a JavaScript/es6 filter?

Hi Chris - thanks for responinding, I am specifically looking for a jq (stedolan.github.io/jq) filter as a solution.

This gets the desired output.

jq '.members |= map(select(.ln == "smith"))'

It updates .members, selecting only objects with .ln == smith

Thank you very much!
