title: CSS selector case insensitive for attributes
body: <p>If I have an HTML element <code>&lt;input type="submit" value="Search" /&gt;</code> a css selector needs to be case-sensitive:</p>
  
  <p><code>input[value='Search']</code> matches</p>
  
  <p><code>input[value='search']</code> does not match</p>
  
  <p><strong>I need a solution where the case-insensitive approach works too.</strong> I am using <strong>Selenium 2</strong> and <strong>Jquery</strong>, so answers for both are welcome.</p>
