Looking for advice: json returned from API with and without brackets

[J-F Gaudreault]

Hi! I getting a json from an API request. I've registered the json in a var.

I'm trying to find a way to get the hostname in the json.
I need to find it even if it has brackets or not.

I only got this far ....


with brackets:

- name: test1
  debug:
    msg: "{{ nagios_xi_hosts | json_query('json.host[0].host_name') }}"

no brackets:

- name: test2
  debug:
    var: nagios_xi_hosts.json.host.host_name

The json... returning a list of 2+ objects.
When the API returns only one object, the brackets are gone.

{
    "nagios_xi_hosts.json.host": [
        {
            "@attributes": {
                "id": "26128"

But when it return multiple entries, which one of them will you have?
If it's the fist element in the list this should work

{{ nagios_xi_hosts.json.host.host_name | default(nagios_xi_hosts.json.host.0.host_name }}

If nagios_xi_hosts.json.host.host_name doesn't exist it will return the host_name in the first list element.
