JSON formatting on register value.

[Anthony Cheng]

I have a playbook that use the S3 module to list items:

- name: List s3 bucket

  local_action:

   module: s3

   bucket: "{{ S3_BUCKET_NAME }}"

   mode: list

 register: S3_LIST_ITEM

The result I output to a file using lineinfile:

 name: Output to folder

  local_action:

   module: lineinfile

   create: yes

    line: "{{ S3_LIST_ITEM.s3_keys }}"

   dest: "{{ S3_BUCKET_FILE }}"

   state: present

However this results in a JSON format:

['HelloWorld.sh', 'bucket1/', 'test1']

I tried using jinja2 filter (from_json), 

e.g. line: "{{ S3_LIST_ITEM.s3_keys }}"| from_json

But that didn't work as it gave me:

fatal: [localhost]: FAILED! => {"failed": true, "msg": "Unexpected templating type error occurred on ({{  S3_LIST_ITEM.s3_keys|from_json }}): expected string or buffer"}

There is also no stdout_lines equivalent so how can I put this in a text format that separate each value in a new line?

FYI I figured it out that I needed to use with_item to parse the JSON.
