搜寻论坛：无法搜寻其中包含表格的帖子

我快写完第一本刮板了！

但是，我遇到了一个麻烦：我似乎无法抓住包含表的帖子（换言之，引用另一篇帖子的帖子）的内容。

这是从汤对象中提取帖子内容的代码。它工作得很好：

    def getPost_contents(soup0bj):

        try:
          soup0bj = (soup0bj)
          post_contents = []

          for content in soup0bj.findAll('', {'class' : 'post_content'}, recursive = 'True'):
             post_contents.append(content.text.strip())

         ...#Error management

         return (post_contents)

这是我需要抓取的示例（以黄色突出显示）：

（URL，以防万一：http : //forum.doctissimo.fr/sante/diabete/savoir-diabetique-sujet_170840_1.htm#t657906）

如何获取突出显示的内容？为什么我当前的getPostcontents函数在此特定实例中不起作用？据我所知，字符串仍然在div class = post_contents下。

这就是我获取BeautifulSoup的方式：

    from bs4 import BeautifulSoup as Soup

    def getHTMLsoup(url):

       try:
          html = urlopen(url)
       ...#Error management

       try:
          soup0bj = Soup(html.read().decode('utf-8', 'replace'))
          time.sleep(5)
       ...#Error management

       return (soup0bj)
