title: Extract exact value from stdout_lines from Ansible debug
body: <p>I got my playbook from which I get value what I need through debug method, However I am not able to get exact value of child of my debug var</p>
  
  <p>Below is my playbook</p>
  
  <pre><code>- hosts: db
    tasks:
    - name: Checking if For Page Life Expectancy.
      win_command: sqlcmd -q "SELECT [object_name],[counter_name],[cntr_value] FROM sys.dm_os_performance_counters WHERE [object_name] LIKE '%Manager%'AND [counter_name] = 'Page life expectancy'"
      register: win_command_result
  
  
    - debug:
        var: win_command_result.stdout_lines.object_name
  </code></pre>
  
  <p>And We get output like this</p>

  <p>We only need value of <strong><em>cntr_value</em></strong> which is <strong><em>238579</em></strong></p>
  
  <p>If i set as I though that cntr_value is child of stdout_lines</p>
  
  <pre><code>  - debug:
        var: win_command_result.stdout_lines.cntr_value
  </code></pre>
  
  <p>It says</p>
  
  <pre><code>ok: [db1.local] =&gt; {
      "win_command_result.stdout_lines.cntr_value": "VARIABLE IS NOT DEFINED!"
  }
  </code></pre>
  
  <p>How do I extract exact value of <strong><em>cntr_value</em></strong></p>
