title: Regular Expression to List accepted words
body: <p>I need a regular expression to list accepted Version Numbers.  ie.  Say I wanted to accept <code>"V1.00"</code> and <code>"V1.02"</code>.  I've tried this <code>"(V1.00)|(V1.01)"</code> which almost works but then if I input <code>"V1.002"</code> (Which is likely due to the weird version numbers I am working with) I still get a match.  I need to match the exact strings.</p>
  
  <p>Can anyone help?</p>
