I need to get only specific parts of the output from Ansible, but it is giving me the whole information. I've tried using filtering unsuccessfully.
This is the playbook I am testing with (it has a loop and is probably what is throwing me off)
- name: PLAYBOOK -> Testing
hosts: esxi
gather_facts: no
vars_files:
- vars.yml
vars:
vmnic:
- vmnic0
- vmnic1
tasks:
- name: Get NIC driver/firmware details - shell
shell: esxcli network nic get -n {{ item }} | grep -e Driver -e Firmware -e Version -e Name
loop: "{{ vmnic }}"
register: nic_details
- name: Output NIC driver/firmware details
debug: var=item.stdout_lines
loop: "{{ nic_details['results'] }}"
This is the output I get for one host, I only need the last bit i.e. Driver Info, Driver, Firmware Version, Version and `Name of each VMNIC.

CodePudding user response：
You can use the map filter to extract one field of a list of dictionaries. It can also be used to map one filter to each items of the list, for example, a from_yaml that could help you have dictionaries out of the string you get in stdout.
Given the task:
- debug:
var: nic_details.results | map(attribute="stdout") | map('from_yaml')
This would result in:
nic_details.results | map(attribute="stdout") | map('from_yaml'):
