How can I pick up name of file in archive and save it as variable?

I hope I can explain this clearly, as I encounter one problem and need to use something apart from simply mv (rename) module in Ansible.

I have a task and one of the problem I encounter is that I need to download one file, which has name file-latest.zip. When I unarchive it, first folder I see will be name file-1.2.20 for example. Now, of that name depends how I am going to organize many files and templates. Next time, behind this file-latest.zip will be updated version or file-1.2.21, which I never know.

I would like somehow, when I unarchive, to save it in some variables latest name of that file and then to work further with that variable, but I am not too sure how to figure this out.

I am very beginner in this and this gave me so many thoughts and could not go around and find solution.

One way, if you do have the folder as an unique direct child of your archive would be to use the parameter list_files: true, and gather the directory.

Given a file file-latest.zip:

$ unzip -l file-latest.zip 
Archive:  file-latest.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
        0  06-13-2022 15:19   file-1.2.21/
        0  06-13-2022 11:01   file-1.2.21/foo
        0  06-13-2022 15:19   file-1.2.21/baz
        0  06-13-2022 15:19   file-1.2.21/bar
---------                     -------
        0                     4 files

The two tasks:

- unarchive:
    src: file-latest.zip
    list_files: true
    dest: /tmp
  register: zip_content

- debug:
    var: zip_content.files[0][:-1]

Would unarchive the zip on the target node and yield:

TASK [unarchive] *************************************************************
changed: [localhost]

TASK [debug] *****************************************************************
ok: [localhost] => 
  zip_content.files[0][:-1]: file-1.2.21

From there, you can use it as is or register it in a variable using the set_fact module, e.g.:

- set_fact:
    archive_version_name: "{{ zip_content.files[0][:-1] }}"
