title: Regex for unclosed HTML tags
body: <p>Does someone have a regex to match unclosed HTML tags? For example, the regex would match the <code>&lt;b&gt;</code> and second <code>&lt;i&gt;</code>, but not the first <code>&lt;i&gt;</code> or the first's closing <code>&lt;/i&gt;</code> tag:</p>
  
  <pre><code>&lt;i&gt;&lt;b&gt;test&lt;i&gt;ing&lt;/i&gt;
  </code></pre>
  
  <p>Is this too complex for regex? Might it require some recursive, programmatic processing?</p>
