title: Unable to get CSS Selector "nth-type" working with WebDriver
body: <p>Though have been able to use simple CSS (just including id, name) but "nth-type" gives up.</p>
  
  <p>Here is the test method -</p>
  
  <pre><code>public static String GetTextByCSSSelector(IWebDriver webDriver, String cssLocator)
      {
          return webDriver.FindElement(By.CssSelector(cssLocator)).Text;
      }
  </code></pre>
  
  <p>and this is the method call -</p>
  
  <pre><code>GetTextByCSSSelector(_webDriver, "css=div#filelist div:nth-child(1)");
  </code></pre>
  
  <p>and this is the exception -</p>
  
  <pre><code>OpenQA.Selenium.WebDriverException : An invalid or illegal string was specified
  </code></pre>
  
  <p>I used the locator mentioned above in Selenium IDE and it does highlight the element.
  Any guess?</p>
