# Python Beautiful Soup Module Beautiful Soup is a Python library for pulling data out of HTML and XML files. It works with your favorite parser to provide idiomatic ways of navigating, searching, and modifying the parse tree. ## Installation ```bash pip install beautifulsoup4 ``` ## Importing ```python from bs4 import BeautifulSoup ``` ## Parsing HTML To parse a document, pass it into the `BeautifulSoup` constructor. ```python html_doc = """ The Dormouse's story

The Dormouse's story

Once upon a time there were three little sisters; and their names were Elsie, Lacie and Tillie; and they lived at the bottom of a well.

""" soup = BeautifulSoup(html_doc, 'html.parser') ``` ## Navigating the Tree ```python print(soup.title) # The Dormouse's story print(soup.title.string) # The Dormouse's story print(soup.p) #

The Dormouse's story

``` ## Searching the Tree ### `find()` and `find_all()` `find()` returns the first match, `find_all()` returns a list of matches. ```python # Find all tags links = soup.find_all('a') for link in links: print(link.get('href')) # Find by ID link2 = soup.find(id="link2") ``` ### CSS Selectors You can use `select()` to find elements using CSS selectors. ```python # Select by class soup.select(".sister") # Select by ID soup.select("#link1") # Nested selection soup.select("p.story a") ``` [[programming/python/python]]
