title: Regex to find text between second and third slashes
body: <p>I would like to capture the text that occurs after the second slash and before the third slash in a string.  Example:</p>
  
  <p>/ipaddress/databasename/</p>
  
  <p>I need to capture only the database name.  The database name might have letters, numbers, and underscores.  Thanks.</p>
