Find All Instances of a Tag with Beautiful Soup
Python
Import and Export
To find all instances of a tag on webpage with Beautiful Soup, we use the find_all function and pass the tag that we want to search for. The function returns a list with all occurrences of the tag in question.
In the example below we are looking for all instances of the h2 tag within a Wikipedia webpage.
1| import requests 2| from bs4 import BeautifulSoup 3| 4| response = requests.get('https://en.wikipedia.org/wiki/FTSE_100_Index') 5| parser = BeautifulSoup(response.content, 'html.parser') 6| 7| h2 = parser.find_all('h2')
