  <p>Im trying to click on this button to move to the login page. 
  my code is :</p>
  
  <pre><code>from selenium import webdriver
  driver = webdriver.Chrome()
  driver.get('http://moodle.tau.ac.il/')
  </code></pre>
  
  <p>thats work fine but i can only find the form by using</p>
  
  <pre><code>loginform = driver.find_element_by_xpath("//form[@id='login']/")
  </code></pre>
  
  <p>I don't know how to get to the button, it's very basic stuff but I didn't find any good example.</p>
