title: Regex pattern to remove unknown number of repeating specified string at the beginning of a string
body: <p>Trying to find a regex pattern that will match a repeating string of words separated by white space, but only if it's at the beginning of a larger string.</p>
  
  <pre><code>"Copy of Copy of Copy of This is my String"
  </code></pre>
  
  <p>I want to get rid of all the "Copy of " strings, so the result is:</p>
  
  <pre><code>"This is my String"
  </code></pre>
  
  <p>The "Copy of " can occur an unknown number of times.  Want to get rid of all of them, but only if they start at the beginning of the string.</p>
  
  <p>I tried: <code>\G(\Copy of )( (?=\1 ))?</code>  This was from an example I saw but couldn't figure out how to modify it to work as I want.</p>
