title: BeautifulSoup findall returning empty list
body: <p>So i'm very new to python and I'm trying to get data from a table from iso-ne.com/isoexpress/ using bs4 and urllib. Here's what I have so far:</p>
  
  <pre><code>from bs4 import BeautifulSoup
  from urllib import urlopen
  website='http://www.iso-ne.com/isoexpress/'
  html=urlopen(website).read().decode('utf-8')
  soup=BeautifulSoup(html, 'html.parser')
  table=soup.find('div', {'class': 'chart'})
  rows=table.find_all('tr')
  for tr in rows:
     col=tr.find_all('td')
      for td in col:
          text=td.find_all(class_='lmp-list-energy')
          print text
  </code></pre>
  
  <p>When I run this, I get 6 empty brackets:</p>
  
  <pre><code>[]
  []
  []
  []
  []
  []
  </code></pre>
  
  <p>the data that I am trying to get is the Five Minute Real Time LMP price for the state of New Hampshire on the iso-ne website</p>
