title: Tosa puzzle with RobotFrameWork: read string text from a certain point till a certain point
body: <p>The source is this obstacle: <a href="https://obstaclecourse.tricentis.com/Obstacles/87912" rel="nofollow noreferrer">https://obstaclecourse.tricentis.com/Obstacles/87912</a></p>
  <p>What I got this far is:</p>
  <pre><code>    *** Settings ***
  Library    Browser
  Library    XML
  Library    Collections
  Library    String
  
  Documentation     BE FAST AUTOMATE
  *** Variables ***
  ${links}=  &lt;isbn&gt;
  ${rechts}=  &lt;/isbn&gt;
  
  *** Test Cases ***
  Execute a for loop only three times
      Open Browser    https://obstaclecourse.tricentis.com/Obstacles/87912
      Click    id=loadbooks
      ${alles}=  Get Text    id=books
  </code></pre>
  <p>This one is mentioned: 'hard'</p>
  <p>The Get Text literally gets all the text which is fine, but from that point I have no clue how the get the isbn (from the specific, or even ... any)</p>
