title: Rsyslog search and replace output
body: <p>I've been scouring through the rsyslog documentation for a way to anonymize mysql log data by removed quoted strings. I've successfully managed to detect strings with sensitive data using the :contains property but I can't seem to find a way to replace. </p>
  
  <p>I've looked through the property options and the regex functionality. I believe I may be missing something because none of those provide a straight way for find and replace.</p>
