title: How to transform HTML to Markdown using Nokogiri?
body: <p>Is there any way to transform HTML into Markdown text? </p>
  
  <ul>
  <li>HTML is pretty simple - it's just a div element with several <code>&lt;p&gt;</code> elements inside.</li>
  <li>There may be images - I want to preserve them as well. </li>
  <li>Also, there may be several "inline" images like this one: <code>&lt;img src='images/symbol_minus.gif' width='9' height='3' alt='&amp;minus;' border='0' style='vertical-align:middle;' /&gt;</code> which is just a minus sign - I want to replace them with text.</li>
  </ul>
  
  <p><code>Nokogiri::XML::Element#text</code> is almost something that I want, but it strips off images.</p>
