I am trying to use BeautifulSoup:

    soup = BeautifulSoup(page)

    td_tags = soup.findAll('td')
    i=0
    for td in td_tags:
        i = i+1
        print "td: ", td
        # re.search('[0-9]*\.[0-9]*', td)
        price = re.compile('[0-9]*\.[0-9]*').search(td)

I am getting an error:

           price= re.compile('[0-9]*\.[0-9]*').search(td)
TypeError: expected string or buffer

Does beautiful soup returns array of objects? If so, how do I pass
"td" instance as string to re.search?  What is the different between
re.search vs re.compile().search?
