title: Replace character in a string with Ansible
body: <p>I have this Ansible as a String:</p>
  
  <pre><code>FUBAR={{ PREFIX }}_{{ CNAME }}{{ VERSION }}
  </code></pre>
  
  <p>I want to replace all <code>.</code> in the concatenated string with <code>''</code>, like this:</p>
  
  <pre><code>FUBAR={{ {{ PREFIX }}_{{ CNAME }}{{ VERSION }} | replace('.','') }}
  </code></pre>
  
  <p>I get the message:</p>
  
  <pre><code>expected token ':', got '}'
  </code></pre>
  
  <p>Could anyone give me a suggestion what's wrong?</p>
