advice on looping through a yaml file and removing key starting with "x-"

[ponsakorn30214]

Hi all,
I'm looking to use yq to loop through an openapi specification (swagger.yaml) file and remove any key(and its value) that started with "x-", the key can be simple key/value, array and object. How should i go to accomplish this?

I've tried yq 'with_entries(select(.key | test("^x-") | not))' swagger.yaml > swagger-kong.yaml but it only removing the key at root level and not deeper level.

Thank you in advance for the answer
