title: string with &lt;tag_name&gt; replace with null
body: <p>I'm just trying to replace the following text without the HTML part like this</p>
  <pre><code>designed to display special types of text:&amp;lt;b&amp;gt;- Bold text&amp;lt;strong&amp;gt;&amp;nbsp;- Important text&amp;lt;i&amp;gt;&amp;nbsp;- Italic text&amp;lt;em&amp;gt;&amp;nbsp;- Emphasized text&amp;lt;mark&amp;gt;&amp;nbsp;- 
  </code></pre>
  <p>using this regular expression replace all between <code>&amp;lt;</code> and <code>&amp;gt;</code> with empty</p>
  <pre><code>html = html.replace(&quot;/(&amp;lt;\/*\w+?&amp;gt;)/g&quot;, '');
  </code></pre>
  <p>but my regular expression seems not working, how to get exact one ?</p>
