Prerequisite- Beautifulsoup module
In this article, we are going to draft a python script that removes a tag from the tree and then completely destroys it and its contents. For this, decompose() method is used which comes built into the module.
Syntax:
Beautifulsoup.Tag.decompose()
Tag.decompose() removes a tag from the tree of a given HTML document, then completely destroys it and its contents.
Implementation:
Example 1:
Python3
# import module from bs4 import BeautifulSoup # URL for scrapping data # get URL html soup = BeautifulSoup(markup, 'html.parser') # display before decompose print("Before Decompose") print(soup.a) # decomposing the # soup data new_tag = soup.a.decompose() print("After decomposing:") print(new_tag) |
Output:
Before Decompose

After decomposing:
None
Example 2: Implementation of given URL to scrape the HTML document.
Python3
# import module from bs4 import BeautifulSoup import requests # Get URL html # Scarping the data from # Html doc reqs = requests.get(url) soup = BeautifulSoup(reqs.text, 'html.parser') # Before decomposing print("Before Decomposing") print(soup) # decompose the soup result = soup.decompose() print("After decomposing:") print(result) |
Output:
Before Decomposing
