Insert a loop variable into json_query in a when condition (ansible) - ansible

Question

I have a json query that returns this result when run using set_fact and displaying using debug:
'''
Json_query: hits | community.general.json_query('results[?item==`xyz`].count')
debug output: TASK [debug] **********************************************************************************************************************************************
ok: [control] => {
"new_list8": "0"
}
Variable used in when conditional
matched: ["0"]
'''
In the JSON_query, "xyz" needs to be substituted by a loop variable in when conditional:
```
**- name: test
community.general.xml:
file: '/home/cloud_user/ansible/ansible_playbook/dev/xmlfiles/test.xml'
#backup: yes
pretty_print: true
xpath: /x:AgentMap
namespaces:
x: http://xyz
add_children:
- env:
name: "{{ server|upper }}"
_:
- agent:
_:
- name: "{{ server }}"
with_items:
- "{{ servers }}"
when: matched[0] in (hits | community.general.json_query('results[?item==`\" + server + \"`].count'))
loop_control:
loop_var: server**
```
Loop variable has been mentioned as seen in
<https://stackoverflow.com/questions/46038985/ansible-pass-a-variable-in-a-json-query-
filter>
When condition always evaluates to false.Task is to add a server to file if it doesn't already exist in it. Mentioned JSON_QUERY is to extract the count value from another task that checks number of occurrences. Query in JPTERM works fine too.`

Answer 1

fo your problem i rewrite your task like this:
```
**- name: test
community.general.xml:
file: '/home/cloud_user/ansible/ansible_playbook/dev/xmlfiles/test.xml'
#backup: yes
pretty_print: true
xpath: /x:AgentMap
namespaces:
x: http://xyz
add_children:
- env:
name: "{{ item|upper }}"
_:
- agent:
_:
- name: "{{ item }}"
when: matched[0] in (hits | community.general.json_query('results[?item==`\" ~ item ~ \"`].count'))
with_items:
- "{{ servers }}"

Answer 2

you cannot use an ansible variable inside the json_query.
specify the jmespath statement in a variable,
then use that in the json_query
- name: test
community.general.xml:
file: '/home/cloud_user/ansible/ansible_playbook/dev/xmlfiles/test.xml'
#backup: yes
pretty_print: true
xpath: /x:AgentMap
namespaces:
x: http://xyz
add_children:
- env:
name: "{{ server|upper }}"
_:
- agent:
_:
- name: "{{ server }}"
loop: "{{ servers }}"
when: matched[0] in (hits | community.general.json_query(my_query)
loop_control:
loop_var: server
vars:
my_query: 'results[?item==`{{ server }}`].count'
