Remove a dict in a nested dict

Hi,
I block on manipuling data with ansible / jinja2 / python filter.

I have this yaml structure which is an ansible inventory in yaml

all:
children:
admin_administration:
hosts:
admin_administration1:
server_ip: 127.0.0.1
int:
children:
int_administration:
int_console:
int_swarmanager:
int_swarmworker:
children:
int_swarmvip:
int_swarminfra:
int_swarmload:
int_scw_swarmload:
int_swarmvip:
hosts:
int_swarmvip1:
server_hostname: swarmvip-001
server_ip: 127.0.0.1

and I have this list of dict:


remove_groups:
- name:
int_swarmworker:
children:
int_swarmvip:

I loop on it so the task gets group.name dict on each iteration

- name: Remove group from inventory file
include_tasks: remove_group.yml
loop: "{{ remove_groups }}"
loop_control:
loop_var: group

In the section:

int_swarmworker:
children:
int_swarmvip:
int_swarminfra:
int_swarmload:
int_scw_swarmload:

Only the int_swarmvip must be removed but if there is no more subobject after removing int_swarmvip below int_swarmworker, the group int_swarmworker must be removed too.

Also this section must be removed:

int_swarmvip:
hosts:
int_swarmvip1:
server_hostname: swarmvip-001
server_ip: 127.0.0.1

So the new yaml ansible inventory should be:

all:
children:
admin_administration:
hosts:
admin_administration1:
server_ip: 127.0.0.1
int:
children:
int_administration:
int_console:
int_swarmanager:
int_swarmworker:
children:
int_swarminfra:
int_swarmload:
int_scw_swarmload:

I did the add_host with ansible dict combine and I try it to remove a dict → fail
Also try a custom plugin fillter → fail
jinja2 code → fail
I debug too much but I’m sure the solution is easy …

Thanks for your help
