title: Remove all attributes from html tags
body: <p>I have this html code:</p>
  <pre><code>&lt;p style=&quot;padding:0px;&quot;&gt;
    &lt;strong style=&quot;padding:0;margin:0;&quot;&gt;hello&lt;/strong&gt;
  &lt;/p&gt;
  </code></pre>
  <p>How can I remove attributes from all tags? I'd like it to look like this:</p>
  <pre><code>&lt;p&gt;
    &lt;strong&gt;hello&lt;/strong&gt;
  &lt;/p&gt;
  </code></pre>
