title: I can't find Web element with xpath using driver.findElement(By.xpath());
body: <p>I tried to find the link on a page to click:</p>
  
  <pre><code>&lt;a id="folder0" class="js-folder icon-wrap icon-wrap_left menu__item__link menu__item__link_act menu__item__link_unread" href="/messages/inbox" rel="history"&gt;
      &lt;span class="js-folder-b-unread js-folder-unread menu__item__link__qnt"&gt;7&lt;/span&gt;
      &lt;i class="js-folder-ico icon icon_left icon_folders icon_inbox_act"&gt;&lt;/i&gt;
      &lt;span class="menu__item__link__text menu__item__link__text_linear"&gt;Input&lt;/span&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>Java code:</p>
  
  <pre><code>driver.findElement(By.xpath(".//*[@id='folder0']/span[2]")).click();
  </code></pre>
  
  <p>But the driver can't locate the element:</p>
  
  <pre><code> org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":".//*[@id='folder0']/span[2]"}
  </code></pre>
