pythonCopy codesoup = BeautifulSoup(html_content, 'html.parser')
Step 5: Extract the Data
Finally, you can extract the data you want from the parsed HTML content. You can do this by using the various methods provided by Beautiful Soup, such as
find_all() to find all instances of a specific HTML tag, or
select() to find elements based on CSS selectors.
pythonCopy code# Extract all links from the HTML content links = soup.find_all('a') # Extract the text content of all paragraphs paragraphs = soup.select('p') text_content = [p.get_text() for p in paragraphs]
