title: Regex to get value from variable String
body: <p>i'm trying to extract a value from a Cookie.  cookies are organized with [name]=[value] pairs separated by a ';'.  so if i have a cookie string like so:</p>
  
  <pre><code>username=user;password=pass;session="4341234556";
  </code></pre>
  
  <p>in this example, i only want the value '4341234556' without the quotes.</p>
  
  <p>the value of the session variable is, of course, different for each request made.  how can i get just the value of session with a regular expression (without the quotes)?  keep in mind that the ordering of the variables is not guaranteed to be the same each time it is returned.</p>
  
  <p>also, i would like to ignore any whitespace characters NOT contained in the value.</p>
