Basic "json_query" features with yaml structures

Hello - i’m trying to figure out how to do this if the data isn’t JSON:

json_query(host[?name==‘webserver’].ipaddress)

In other words, I want to return an attribute from a list based on a condition. I’m trying to combine data from multiple lists over a shared key.

example:

  • system1

  • host: demo1
    ipaddress: 192.168.20.20

  • host: demo4
    ipaddress: 192.168.20.30

  • systemstatus

  • system: demo4
    status: faulty

  • system: web5
    status: operational

What I would like returned is a single list:
result:

  • host: demo4
    ipaddress: 192.168.20.30
    status: faulty

Currently I’m just looping through “systemstatus” but I how do you do the simple json query above to extract the data from “example”. Or if it helps, I am getting data from a 3rd system and I would like to use it to update the inventory data I have about hosts “I know about”. And I keep coming up short on how to select from an list based on a condition that isn’t the index of the array it’s implemented in.
