title: Multiline string to dictionary
body: <p>Let's say that I have the following multiline string. We can assume that title is always followed by a line.</p>
  <pre><code>&quot;&quot;&quot;
  This is title
  -------------------------
  Author: Name of the author
  
  Sentence 1.
  
  Sentence 2.
  &quot;&quot;&quot;
  </code></pre>
  <p>And I want to convert that to a dict like this:</p>
  <pre><code>{
      &quot;title&quot;: &quot;This is title&quot;,
      &quot;author&quot;: &quot;Name of the author&quot;,
      &quot;body&quot;: &quot;sentence 1.\n\nSentence 2.&quot;,
  }
  </code></pre>
  <p>How can I split the first two lines with all those &quot;-----&quot; and later split the rest of the line by new line? Could you please give me some suggestions?</p>
