title: using regex_findall to filter output
body: <p>I am using regex find_all to filter the output of network command, I've tested the regex with the output using regex101 and I'am sure it's correct, the output is also as expected but when I try to filter I think it don't match in the playbook. I always get a blank msg as a result.</p>
  
  <pre><code>- name: extract env
   lineinfile:                                 
     line: "{{ env.stdout[0] }}"
     dest: "{{ output_path }}/env_of_{{inventory_hostname}}.csv"
     create: True
  -  debug:
     msg: "{{ env.stdout[0] | regex_findall('^.*one minute: (\\d+%); five.*$') }}"
  </code></pre>
  
  <p>The output should be a number in percent but this is what I get:</p>
  
  <pre><code>TASK [debug] ********************************************************************************************************
  task path: /ansible/testcsv.yml:60
  ok: [R1] =&gt; {

   }

   }
  ok: [R3] =&gt; {

   }
