title: How to use regex to parse a number from HTML?
body: <p>I want to write a simple regular expression in Python that extracts a number from HTML. The HTML sample is as follows:</p>
  <pre><code>Your number is &lt;b&gt;123&lt;/b&gt;
  </code></pre>
  <p>Now, how can I extract &quot;123&quot;, i.e. the contents of the first bold text after the string &quot;Your number is&quot;?</p>
