title: What would the Jsoup selector be for TD elements that have no children and no COLSPAN attribute?
body: <p>So I'm trying to parse through a web page that is relatively messy.  It contains several key-value pairs that I would like to extract.  The unifying theme of these pairs is that they are non-empty, they have no children, and they do not have a COLSPAN attribute.  Here's what I've tried, which seems to make sense logically but does not yield any results.</p>
  
  <pre><code>Elements tds = document.select("td:not([colspan]):not(:has(*))");
  </code></pre>
  
  <p>So I want TDs that:</p>
  
  <ol>
  <li>Do not contain COLSPAN</li>
  <li>Do not have any children</li>
  </ol>
  
  <p>Seems like I must be close, but just not having any luck.  Any thoughts?</p>
