title: Get substring with Robot Framework
body: <p>I have a string &quot;banana :is_good OR :bad and apple :is_sweet OR :bitter and...&quot;</p>
  <p>I want to get all the characters between &quot;:&quot; characters.</p>
  <p>(so in upper case I would get &quot;is_good OR &quot; and &quot;is_sweet OR &quot;)</p>
  <p>What is the simplest way to do it with Robot Framework? Substring/Get Regexp Matches/?</p>
  <p>Or if it is better to do with Python, how to do it?</p>
