title: How to select following sibling tag with xpath
body: <p>I have a HTML file like this:</p>
  
  <pre><code>&lt;div id="note"&gt;
   &lt;a name="overview"&gt;&lt;/a&gt;
   &lt;h3&gt;Overview&lt;/h3&gt;
   &lt;p&gt;some text1...&lt;/p&gt;
   &lt;a name="description"&gt;&lt;/a&gt;
   &lt;h3&gt;Description&lt;/h3&gt;
   &lt;p&gt;some text2 ...&lt;/p&gt;
  &lt;/div&gt;
                                `
  </code></pre>
  
  <p>I would like to retrieve the paragraph, for each header.
  for example, overview: some text1
  description: some text 2 
  ...
  I want to write this in python using xpath.
  Thank you.</p>
