title: Get string between two strings in a string
body: <p>I have a string like:</p>
  <pre><code>&quot;super example of string key : text I want to keep - end of my string&quot;
  </code></pre>
  <p>I want to just keep the string which is between <code>&quot;key : &quot;</code> and <code>&quot; - &quot;</code>.  How can I do that?  Must I use a Regex or can I do it in another way?</p>
