Find all element by class or other parameters in Beautiful Soup

Here are a couple of ways to search the soup for certain tags, or tags with certain properties:

titleTag = soup.html.head.title
titleTag
# 

titleTag.string
# u'Page title'

len(soup('p'))
# 2

soup.findAll('p', align="center")
# [
This is paragraph one. ]

soup.find('p', align="center")
# 
This is paragraph one. 

soup('p', align="center")[0]['id']
# u'firstpara'

soup.find('p', align=re.compile('^b.*'))['id']
# u'secondpara'

soup.find('p').b.string
# u'one'

soup('p')[1].b.string
# u'two'
