Prerequisite: BeautifulSoup
BeautifulSoup(bs4) is a Python library for pulling data out of HTML and XML files. This module does not come in built-in with Python. To install this type the below command in the terminal. In this article, we will learn about siblings in HTML tags using BeautifulSoup.
Here we will discuss these four sibling properties:
- previous_sibling is used to find the previous element of the given element
- next_sibling is used to find the next element of the given element
- previous_siblings is used to find all previous element of the given element
- next_siblings is used to find all next element of the given element
Approach
- Import module
- Load or create HTML code
- Parse HTML code
- Print required sibling.
Example 1: To print next immediate sibling
Python3
# Import Module from bs4 import BeautifulSoup # HTML CODE html_code = """<a><b>text1</b><c>text2</c></a>""" # Parse HTML CODE soup = BeautifulSoup(html_code, 'html.parser') # next element print(soup.b.next_sibling) |
Output:
<c>text2</c>
Example 2: To get previous immediate sibling
Python3
# Import Module from bs4 import BeautifulSoup # HTML CODE html_code = """<a><b>text1</b><c>text2</c></a>""" # Parse HTML CODE soup = BeautifulSoup(html_code, 'html.parser') # previous element print(soup.c.previous_sibling) |
Output:
<b>text1</b>
Suppose we want to find all the next elements of a tag. For that, we just simply iterate through siblings and print the required tag.
Example 3: To get all siblings next to the tag
Python3
# Import Module from bs4 import BeautifulSoup # HTML CODE html_code = """<a><b>text1</b><d>text3</d><c>text2</c></a>""" # Parse HTML CODE soup = BeautifulSoup(html_code, 'html.parser') # next element for element in soup.b.next_siblings: print(element) |
Output:
<d>text3</d>
<c>text2</c>
Example 4: To get all previous siblings
Python3
# Import Module from bs4 import BeautifulSoup # HTML CODE html_code = """<a><b>text1</b><d>text3</d><c>text2</c></a>""" # Parse HTML CODE soup = BeautifulSoup(html_code, 'html.parser') # previous element for element in soup.c.previous_siblings: print(element) |
Output:
<d>text3</d>
<b>text1</b>
