title: Regex remove everything after last occasion of semicolon
body: <p>i have for example this string:</p>
  
  <blockquote>
    <p>hello; how; are; you; ?</p>
  </blockquote>
  
  <p>and i need to delete everything after last occasion of semicolon. I know that it is easy but i haven't a lot of time to learn regular expressions.  Im using text editor PSPad which supports regular expressions functions and the text is in simple txt file.</p>
  
  <p>Thank you</p>
