I explain:
I have this code json:

{
"TAB": "bleu",
"exp": [
{
"A": "NOT_PROTECTED",
"B": [
"500",
"600"
],
"C": false
}
],
"ID": "000041"
},
{
"TAB": "rouge",
"exp": [
{
"A": "PROTECTED",
"B": [
"700",
"800"
],
"C": true
}
],
"ID": "000042"
}
]
}

I'm assuming the question is how you access the values in Ansible, since it has the ansible tag.
You can use the map filter in Ansible to access the values like so: (where your json is in the some_json variable.)
- debug:
msg: "{{ some_json.results | map(attribute='ID') | list }}"
results:
ok: [localhost] => {
"msg": [
"000041",
"000042"
]
}
If you want to do it with json_query/jmespath (As the question is also tagged with json_query and jmespath) then it would be like this:
- debug:
msg: "{{ some_json.results | json_query('[*].ID') | list }}"
ok: [localhost] => {
"msg": [
"000041",
"000042"
]
}
That being said, I do prefer the map method myself since it does not require any extra dependencies where as json_query requires jmespath to be installed.
