Anlible. How do I add a condition to a loop operation? - ansible

Question

How can I get from this data only the value ("subclientName": "test") where "count" = 1
"subclientName": "start9pm" should not be in the selection
{
"countbackupsetName": {
"results": [
{
"actions": {
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"test\"]]/vmContent/children",
"namespaces": {},
"state": "present"
},
"changed": false,
"count": 2,
"msg": "found 2 nodes",
"invocation": {
"module_args": {
"path": "/var/lib/awx/projects/commv/parse/get_subclient2.xml",
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"test\"]]/vmContent/children",
"count": true,
"namespaces": {},
"state": "present",
"print_match": false,
"pretty_print": false,
"input_type": "yaml",
"backup": false,
"strip_cdata_tags": false,
"insertbefore": false,
"insertafter": false,
"xmlstring": null,
"value": null,
"attribute": null,
"add_children": null,
"set_children": null,

}
},
"failed": false,
"item": {
"appName": "Virtual Server",
"backupsetName": "backupset-test",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "test"
},
"ansible_loop_var": "item"
},
{
"actions": {
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"start9pm\"]]/vmContent/children",
"namespaces": {},
"state": "present"
},
"changed": false,
"count": 2,
"msg": "found 2 nodes",
"invocation": {
"module_args": {
"path": "/var/lib/awx/projects/commv/parse/get_subclient2.xml",
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"start9pm\"]]/vmContent/children",
"count": true,
"namespaces": {},
"state": "present",
"print_match": false,
"pretty_print": false,
"input_type": "yaml",
"backup": false,
"strip_cdata_tags": false,
"insertbefore": false,
"insertafter": false,
"xmlstring": null,
"value": null,
"attribute": null,
"add_children": null,
"set_children": null,

}
},
"failed": false,
"item": {
"appName": "Virtual Server",
"backupsetName": "Test01",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "start9pm"
},
"ansible_loop_var": "item"
}
],
"msg": "All items completed",
"changed": false
},
"_ansible_verbose_always": true,
"_ansible_no_log": false,
"changed": false
}
This is how I managed to select everything, without the condition operation:
- debug:
msg: "{{ item.subclientName }}"
loop: "{{ countbackupsetName.results|map(attribute='item')|list }}"
result:
{
"msg": "test",
"_ansible_verbose_always": true,
"_ansible_no_log": false,
"changed": false,
"item": {
"appName": "Virtual Server",
"backupsetName": "backupset-test",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "test"
},
"ansible_loop_var": "item",
"_ansible_item_label": {
"appName": "Virtual Server",
"backupsetName": "backupset-test",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "test"
}
}
This is how I get to the data I need, but the number of lines is always different.
I also don't need lines where count ":" 2 "
code:
- name: Show value in countbackupsetName.results.0.count
debug:
var: countbackupsetName.results.0.count
- debug:
var: countbackupsetName.results.0.item.subclientName
- name: Show value in countbackupsetName.results.1.count
debug:
var: countbackupsetName.results.1.count
- debug:
var: countbackupsetName.results.1.item.subclientName
result:
TASK [Show value in countbackupsetName.results.0.count] ************************
ok: [localhost] => {
"countbackupsetName.results.0.count": "1"
}
TASK [debug] *******************************************************************
ok: [localhost] => {
"countbackupsetName.results.0.item.subclientName": "test"
}
TASK [Show value in countbackupsetName.results.1.count] ************************
ok: [localhost] => {
"countbackupsetName.results.1.count": "2"
}
code:
- name: debug jinja
debug:
msg: |
[
{% for p in countbackupsetName.results %}
{% for o in countbackupsetName.results[p].item %}
{
"count": "{{ countbackupsetName.results[p].count }}",
"key": "{{ o }}",
"value": "{{ countbackupsetName.results[p].item[o] }}"
},
{% endfor %}
{% endfor %}
]
result:
line 112, column 9, but may\nbe elsewhere in the file depending on the exact syntax problem.

Not sure I've got properly what is desired output. But idea should be the same regardless: loop through results checking for condition and printing matching items. Here you go:
- hosts: localhost
become: false
tasks:
- set_fact:
data: {
"countbackupsetName": {
"results": [
{
"actions": {
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"test\"]]/vmContent/children",
"namespaces": {},
"state": "present"
},
"changed": false,
"count": 2,
"msg": "found 2 nodes",
"invocation": {
"module_args": {
"path": "/var/lib/awx/projects/commv/parse/get_subclient2.xml",
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"test\"]]/vmContent/children",
"count": true,
"namespaces": {},
"state": "present",
"print_match": false,
"pretty_print": false,
"input_type": "yaml",
"backup": false,
"strip_cdata_tags": false,
"insertbefore": false,
"insertafter": false,
"xmlstring": null,
"value": null,
"attribute": null,
"add_children": null,
"set_children": null,
"content": null
}
},
"failed": false,
"item": {
"appName": "Virtual Server",
"backupsetName": "backupset-test",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "test"
},
"ansible_loop_var": "item"
},
{
"actions": {
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"start9pm\"]]/vmContent/children",
"namespaces": {},
"state": "present"
},
"changed": false,
"count": 2,
"msg": "found 2 nodes",
"invocation": {
"module_args": {
"path": "/var/lib/awx/projects/commv/parse/get_subclient2.xml",
"xpath": "//subClientProperties[subClientEntity[#subclientName=\"start9pm\"]]/vmContent/children",
"count": true,
"namespaces": {},
"state": "present",
"print_match": false,
"pretty_print": false,
"input_type": "yaml",
"backup": false,
"strip_cdata_tags": false,
"insertbefore": false,
"insertafter": false,
"xmlstring": null,
"value": null,
"attribute": null,
"add_children": null,
"set_children": null,
"content": null
}
},
"failed": false,
"item": {
"appName": "Virtual Server",
"backupsetName": "Test01",
"clientName": "name05-vcagent",
"displayName": "name05-VCAgent",
"instanceName": "VC01",
"subclientName": "start9pm"
},
"ansible_loop_var": "item"
}
],
"msg": "All items completed",
"changed": false
},
"_ansible_verbose_always": true,
"_ansible_no_log": false,
"changed": false
}
- debug:
var: result
# check for condition in result
when: result['item']['subclientName'] == "test"
# iterate over result list
loop: "{{ data['countbackupsetName']['results'] }}"
# set loop_var to not confuse ansible's "item" var with "item" key in data
loop_control:
loop_var: result

Was able to solve the problem using json_query!
code:
- set_fact:
add_filter: "{{ countbackupsetName|json_query(query2) }}"
vars:
query2: "results[?count==`1`].item.subclientName"
- name: debug json_query(query2)
debug:
var: add_filter
result:
TASK [debug json_query(query2)] ************************************************
ok: [localhost] => {
"add_filter": [
"test"
]
}
code:
- set_fact:
add_filter: "{{ count_add_hostname.results|json_query(_query) }}"
vars:
_query: "[].{subclientName: '[?count==`1`]'.item.subclientName,
backupsetName: '[?count==`1`]'.item.backupsetName}"
- name: debug json_query(add_filter)
debug:
var: add_filter
I try to execute in a loop
result:
TASK [debug json_query(add_filter) var=add_filter] *****************************
ok: [localhost] => {
"add_filter": [
{
"backupsetName": null,
"subclientName": null
},
{
"backupsetName": null,
"subclientName": null
},
{
"backupsetName": null,
"subclientName": null
}
]
}
is the empty result related to a conflict in the loop item and the dictionary name item ...
