title: Unable to parse data inside h4 tag: Python3
body: <p>I am facing an issue while parsing data from the 'Literature ' tab from the third table. The steps I took to reach the table:</p>
  
  <ul>
  <li><p>Go to ibl.mdanderson.org/fasmic/#!</p></li>
  <li><p>Type and select AKT1 (3 mutations) (NOTE:'GO' button doesn't work, please click the option from the drop-down)</p></li>
  <li><p>Click on the green button with the text 'MS', a new table will appear.</p></li>
  <li><p>In this new table, there will be a tab called literature, I need the literature text and the PMID.</p></li>
  </ul>
  
  <p>I tried the following code, but it gives an empty list:</p>
  
  <pre><code>xyz= driver.find_element_by_xpath("//*[contains(text(),'Literature')]").click()
      for elements in driver.find_elements_by_xpath('//div[@class="tab-pane ng-scope active"]'):
  
          soup = BeautifulSoup(driver.page_source, 'lxml')
          table = soup.find('div', attrs={'id': "literature_div"})
          table_body = table.find('h4')
          rows = table.find_all('h4')
          for row in rows:
               cols = row.find_all('h4')
               # cols = [ele.text.strip() for ele in cols]
               litrature.append([ele for ele in cols if ele])  # Get rid of empty value
               print("Data from COLUMN 1:")
               print(litrature)
  </code></pre>
  
  <p>How can I resolve this?</p>
  
  <p><strong>UPDATE</strong>
  When I try to click on the 'Next ' button under the 'literature' table, I get the following error:
   "Message: The element reference of  is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed " 
  Following is the line I added to click on the "NEXT" buton: <code>driver.find_element_by_xpath('//a[@ng-click="selectPage(page + 1, $event)"]').click()</code></p>
  
  <p>How can I resolve this?</p>
