title: Extracting tables containing a string with BeautifulSoup
body: <p>I am trying to parse a website which contains many tables within tables within tables etc, using BeautifulSoup. Specifically I am looking at <a href="http://www.footywire.com/afl/footy/ft_match_statistics?mid=5634&amp;advv=Y" rel="nofollow">websites of this form</a>. I could like to extract the relevant tables, e.g. those of match statistics, but can't seem to find a way to extract the relevant tables, as they don't contain distinguishing features such as a particular class etc.</p>
  
  <p>Is there a way to extract tables which contain certain strings?</p>
