title: how do I pattern match a string within a string and then extract it into a variable
body: <p>I have come across a problem that I cannot see to solve. I have extracted a line from a web page into a variable. lets say for argument sake this is:</p>
  
  <p>rhyme = "three blind mice Version 6.0"</p>
  
  <p>and I want to be able to first of all locate the version number within this string (6.0) and secondly extract this number into another seperate variable - (I want to specifically extract no more than "6.0")</p>
  
  <p>I hope I have clarified this enough, if not please ask me anything you need to know and I will get back to you asap.</p>
