Prerequisite: Implementing Web Scraping in Python with BeautifulSoup
In this article, we are going to see how to extract CSS from an HTML document or URL using python.
Module Needed:
- bs4: Beautiful Soup(bs4) is a Python library for pulling data out of HTML and XML files. This module does not come built-in with Python. To install this type the below command in the terminal.
pip install bs4
- requests: Requests allows you to send HTTP/1.1 requests extremely easily. This module also does not comes built-in with Python. To install this type the below command in the terminal.
pip install requests
Approach:
- Import module
- Create an HTML document and specify the CSS tag into the code
- Pass the HTML document into the Beautifulsoup() function
- Now traverse the tag with the select() method.
Implementation:
Python3
from bs4 import BeautifulSoup
html_doc =
soup = BeautifulSoup(html_doc, "lxml" )
print ( "display by CSS class:" )
print (soup.select( ".example" ))
|
Output:
display by CSS class:
[<a class="example" href="www.geeksforgeeks.com" id="dsx_23">java</a>,
<a class="example" href="www.geeksforgeeks.com/python" id="sdcsdsdf">python</a>]
Now let’s get the CSS tag with URL:
Python3
from bs4 import BeautifulSoup
import requests
def getdata(url):
r = requests.get(url)
return r.text
soup = BeautifulSoup(html_doc, "lxml" )
print ( "\nTags by CSS class:" )
print (soup.select( ".header-main__wrapper" ))
