title: beautifulsoup doesn't show all ellements
body: <p>i'm trying to parse Taobao website and get information about Goods (photo , text and link ) with BeautifulSoup.find but it doesn't find all classes.</p>
  
  <pre><code>url='https://xuanniwen.world.tmall.com/category-1268767539.htm?search=y&amp;catName=%BC%D0%BF%CB#bd&amp;view_op=citations_histogram'
  
  def get_html(url):
      r = requests.get(url)
      return r.text
  
  html=get_html(url)
  soup=BeautifulSoup(html, 'lxml')
  z=soup.find("div",{"class":"J_TItems"})
  </code></pre>
  
  <p>z-is empty.
  but for example:</p>
  
  <pre><code>z=soup.find("div",{"class":"skin-box-bd"})
  len(z)
  Out[196]: 3
  </code></pre>
  
  <p>works fine</p>
  
  <p>Why this approach doesn't work? What should i do to get all information about good? i am using python 2.7</p>
