BeautifulSoup - Wrap an element in a new tag

In BeautifulSoup, a Python library for parsing HTML and XML documents, you can wrap an element in a new tag using the wrap() method. This method allows you to enclose a BeautifulSoup object in a new tag, effectively nesting the original element inside a new one. Here's an example to demonstrate this:

Example: Wrapping an Element in a New Tag

First, ensure you have BeautifulSoup installed. If not, you can install it via pip:

pip install beautifulsoup4

Sample HTML

Consider this sample HTML content:

<html> <head> <title>Test Page</title> </head> <body> <p id="first">This is a paragraph.</p> <p>Another paragraph.</p> </body> </html>

Wrapping an Element

Let's say you want to wrap the first paragraph (<p id="first">) in a <div> tag.

from bs4 import BeautifulSoup # Sample HTML html_doc = """ <html> <head> <title>Test Page</title> </head> <body> <p id="first">This is a paragraph.</p> <p>Another paragraph.</p> </body> </html> """ # Create a BeautifulSoup object soup = BeautifulSoup(html_doc, 'html.parser') # Find the paragraph you want to wrap p_tag = soup.find('p', id='first') # Create a new tag to wrap around the paragraph new_tag = soup.new_tag('div') # Wrap the paragraph in the new tag p_tag.wrap(new_tag) # Print the modified HTML print(soup.prettify())

Explanation

  • BeautifulSoup(html_doc, 'html.parser'): Parses the HTML content.
  • soup.find('p', id='first'): Finds the first <p> tag with the id 'first'.
  • soup.new_tag('div'): Creates a new <div> tag.
  • p_tag.wrap(new_tag): Wraps the found <p> tag in the newly created <div> tag.

After running this script, the first paragraph in the HTML will be enclosed within a <div> tag. The wrap() method is a convenient way to modify the structure of an HTML document using BeautifulSoup.
