title: Anything before and after delimiter regex
body: <pre><code>(?=.+?,*)[^,]+
  </code></pre>
  
  <p>There are the results I get and expect:</p>
  
  <p>"This,is,successful"</p>
  
  <p>Results:</p>
  
  <ul>
  <li>This</li>
  <li>is</li>
  <li>successful</li>
  </ul>
  
  <p>",is also successful"</p>
  
  <p>Results:</p>
  
  <ul>
  <li>is also successful</li>
  </ul>
  
  <p>The following is wrong-</p>
  
  <p>"This is not successful"</p>
  
  <p>Results:</p>
  
  <ul>
  <li>This is not successful</li>
  </ul>
  
  <p>I only want to match if and only if the delimiter is in the string, anything before and after the delimiter. I tried an additional look ahead with <code>+.</code>. but was either getting results that include everything or nothing at all when a delimiter like ',' was present.</p>
