How do we do a wildcard search with Ansible nested variable?

- debug:
    msg: >-
      {{ test.name
      | dict2items
      | selectattr("key", "match", "addr.*")
      | map(attribute="value.zipcode")
      | list }}

Where dict2items explodes the children of name allowing one to pattern match -- or any other fun tricks -- based on the key of the dict, which ordinarily -- as you have seen -- isn't possible

Then we now have a list of matching {"key": "address1234", "value": {"zipcode": "11111"}} structures, so if you want the zipcode field of all of them, just reach into the value dict and pull out its zipcode field.

The final list is a concession because map produces a python generator, and not an actual list
