title: Unable to locate element using selenium webdriver in python
body: <p>I want to do some automation testing on a website called <a href="http://elegalix.allahabadhighcourt.in" rel="nofollow noreferrer">http://elegalix.allahabadhighcourt.in</a>. I am using the following python code to click a button called "Advanced" on the above website:</p>
  
  <p>Code# </p>
  
  <pre><code>from selenium import webdriver
  driver = webdriver.Chrome('./chromedriver')
  driver.get('http://elegalix.allahabadhighcourt.in')
  driver.set_page_load_timeout(20)
  driver.maximize_window()
  driver.find_element_by_xpath("//input[@value='Advanced']").click()
  </code></pre>
  
  <p>Error#</p>
  
  <pre><code>selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //input[@value='Advanced']
  </code></pre>
  
  <p>P.S I am a newbie to python programming. I have tried different variations of xpath and have tried to use other find_element_by methods but none seems to work on this website...I m experiencing similar error on Firefox browser as well...</p>
