title: Hide a tr only if td contains no content AFTER a specific html tag
body: <p>Is it possible to examine the content within a tr, AFTER an html element (br) to see if any exists? If there is no content after the br element, I'd like to hide the parent td. Please note that the html code is system generated and I cannot edit it.</p>
  
  <p>I'm just not sure where to begin with this. Any help is greatly appreciated.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>    &lt;table class="tabledefault"&gt;

                  &lt;table class="tabledefault"&gt;
                      &lt;tbody&gt;
                          &lt;tr&gt;&lt;!-- this TR should be hidden --&gt;
