Working with Specific Elements

Navigating an HTML document using Python attributes will retrieve only the first occurrence of a particular element. But what if you're interested in the first instance of an element and don't know its full path? In such cases, you can utilize the .find() method, passing the tag (without < > brackets) as a string. For example, let's locate the first <div> element in the HTML document.


              123456789101112
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/jesus.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
print(soup.find('div'))

Furthermore, you can retrieve all instances of a specific element by employing the .find_all() method. This will yield a list of instances. For instance, let's locate all the <p> tags in the HTML document.


              123456789101112
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/jesus.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
print(soup.find_all('p'))

You can also use the .find_all() method to find not just one but multiple tags by providing a list of tags. For example, let's gather all the <div> and <title> elements.


              12345678910111213
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/page.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
for el in soup.find_all(["div", "title"]):
  print(el)
