ansible.builtin.regex_findall filter – extract all regex matches from string
Note
This filter plugin is part of ansible-core
and included in all Ansible
installations. In most cases, you can use the short

regex_findall

However, we recommend you use the FQCN for easy linking to the
plugin documentation and to avoid conflicting with other collections that may have
the same filter plugin name.
