title: Google Sheets - Remove all HTML tags except <img> and <a> tags
body: <p>I have a Google Sheets document with data from a web scrape. I'd like to remove all HTML tags except links and images. I have managed to remove all HTML with the REGEXREPLACE function:</p>
  <pre><code>=REGEXREPLACE(A1;&quot;&lt;/?\S+[^&lt;&gt;]*&gt;&quot;;&quot;&quot;)
  </code></pre>
  <p>...but I want to keep img and a-tags</p>
  <p>Please help!</p>
