title: Separation from URL the scrape of text
body: <p>I have a some URL like this: </p>
  
  <p><code>http://www.newspaper.pl/abcd/bcda.dll/article?AID=/20140128/XXX/140129527</code></p>
  
  <p>and want to separate this scrape of text </p>
  
  <pre><code>20140128/XXX/140129527
  </code></pre>
  
  <p>but only when URL have this scrape of text</p>
  
  <pre><code>article?AID=/
  </code></pre>
  
  <p>I have tried function "substring" but all of my options were wrong. What's more sometimes url doesn't end like this, but have sign &amp; etc., like this</p>
  
  <p><code>http://www.newspaper.pl/abcd/bcda.dll/article?AID=/20140128/XXX/140129527&amp;photo1</code></p>
  
  <p>and I also want to separate the same scrape of text without <code>&amp;photo1</code></p>
  
  <p>Do you have any idea? This scrape of text <code>'XXX/140129527'</code> hasdifferent length. I really couldn't find the solution of this problem on stack.</p>
