<p class="story">Once upon a time there were three little sisters; and their names were
<a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,
and they lived at the bottom of a well.</p>

<p class="story">some sample data
<a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>
and they lived at the bottom of a well.

<a href="http://example.com/samplelink" class="sister" id="link2">Tillie</a>
<a href="http://example.com/samplelink2" class="sister" id="link2">Tillie</a>
some dummy data
</p>

</body>
</html>
"""   
     

Extract document title.

   
# Extract title and title text
print(soup.title)
print(soup.title.string)
 

Extract all <p> tags.

   
# Extract all p tags
p_tags = soup.find_all("p")
print(p_tags)
 

Extract <p> tag with class name "story".

   
# Extract p tag with class name "story"
print(soup.find_all("p",attrs={'class':"story"}))
 

Extract all <a> tags

   
# Extract all a tags
a_tags = soup.find_all("a")
print(a_tags)
 

Extract all urls from <a> tags.

   
# Extract all urls from a tags 
for a in a_tags:
    print(a.get('href'))
 

Extract all elements with id link2.

   
# Extract all elements with id link2
print(soup.find_all(id="link2"))
