title: how to print everything after keyword ? for instance print everything between word "Apple" and word "Pen"
body: <p>I need to make a script what showing me all the characters in between the keywords.</p>
  
  <p>Let's say, I download html page and then read it (it has 33985 characters in there). I need to print everything between <code>"&lt;td class="ml_subject"&gt;&lt;a href="?tab=inbox"</code> and <code>"&lt;/a&gt;&lt;/td&gt;"</code> which is dozen letters away.</p>
  
  <p>I can find the start point by using:</p>
  
  <pre><code>if "&lt;td class="ml_subject"&gt;&lt;a href="?tab=inbox" in html:
      print "Success"
  </code></pre>
  
  <p>but what's then ?</p>
