title: Regex to extract text after a pattern
body: <p>I am trying to extract the Error Messages from loader output like below :</p>
  <pre><code>LOADER_ERROR : *** Failure The UserId, Password or Account is invalid., attempts:1
  LOADER_ERROR : *** Time out waiting for a response.
  </code></pre>
  <p>Expected Output :</p>
  <pre><code>Failure The UserId, Password or Account is invalid., attempts:1
  Time out waiting for a response.
  </code></pre>
  <p>With the below regex, I am able to extract everything after the last occurrence of ': ' character.</p>
  <pre><code>  .+(\:\s.+)$
  </code></pre>
  <p>Output :</p>
  <pre><code>: *** Failure The UserId, Password or Account is invalid., attempts:1
  : *** Time out waiting for a response.
  </code></pre>
  <p>How do I strip ': ' or '*** ' at the beginning from the output ?</p>
  <p>Thanks for any assistance</p>
