Filter specific string from file content and it needs to be looped into mail module

[Pandu jh]

I have multiple files in a path and it contains mail id of the users. 

I need to loop the file content using with_items and filter users ID from the file content.

That ID's should be passed into mail module, mail needs to be sent to those user ID's. 

Please help me filter only ID form the file content and it needs to be looped into mail module.

cat /test/user1

Name: Anton

ID: ant...@xxx.com

cat /test/user2

Name: Jeniffer

ID: jenni...@xxx.com

      - shell:  cat {{ item }}  | egrep -v 'provided|valid'

        register: file_content

        with_items:

          - /test/user1

          - /test/user2

      - name: Send mail notification to the user

        mail:

          host: mailrelay.xxx.com

          port: 25

          subject:  Information

          body: "{{ lookup('file', '{{  req_path  }}/{{ req }}') + lookup('file', '{{ mail_sign  }}') }}"
