title: Parse and traverse elements from a Markdown file
body: <p>I want to parse and then traverse a Markdown file. I'm looking for something like <a href="https://docs.python.org/2.7/library/xml.etree.elementtree.html" rel="noreferrer">xml.etree.ElementTree</a> but for Markdown. </p>
  
  <p>One option would be to convert to HTML and then use another library to parse the HTML. But I'd like to avoid that step.</p>
  
  <p>Thanks.</p>
