title: selenium-webdriver click the first link
body: <p>I'm using selenium-webdriver and i'm looking for something really simple but I didn't find it in the documentation.</p>
  
  <p>This is a part of my code :</p>
  
  <pre><code>browser = Selenium::WebDriver.for :firefox, :profile =&gt; profile
  browser.navigate.to 'an_url'
  # I find ancestor element
  browser.find_element(:id, "displaylinks").find_element(:id, "link0").find_element(:class, "link-center")
  # but I want to click the first link child of this last element
  </code></pre>
  
  <p>Any ideas ?</p>
