[Plugin: Posts By Tag] Can I edit the code output?

As it stands now, the plugin outputs this code (with thumbnail, date and excerpt options set to true):

<ul>
  <li>
    <a><img/></a>
    <a>TITLE</a>
    <small>DATE</small><br/>
    EXCERPT
  </li>
</ul>

Ideally, I’d like to use div’s and span’s instead of ul/li, small and br; can I edit the output somehow?
