Navigating HTML Document

After reading the HTML document, you have the flexibility to navigate it in several ways. To delve deeper, you can specify a tag just like an attribute. For example, let's examine the <head> element and represent it in a 'structured' form (by employing the .prettify() method).


              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.head.prettify())

Feel free to experiment by substituting the .head attribute with .body, for example. As shown above, the <head> element encompasses several children. You can iterate through all the children of elements using a for loop and the .children attribute.


              1234567891011121314
            
# Importing libraries

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')
# Iterating over all element children
for child in soup.head.children:
  print(child)
