This library helps in navigating, searching, and modifying the parse tree structure. Some key features of BeautifulSoup include: 1. Parsing: BeautifulSoup can parse HTML or XML documents and create a parse tree, which allows easy navigation and extraction of data. 2. Searching: It provides various methods to search for specific elements in the parse tree based on their tag names, attributes, text content, etc. 3. Modifying: BeautifulSoup allows modifying elements in the parse tree by adding, removing, or modifying attributes and contents of tags. 4. Pretty printing: It can format the parsed document in a visually appealing way by indenting tags and aligning them properly. Overall, BeautifulSoup simplifies the process of web scraping by providing an intuitive API to work with HTML and XML documents. It is widely used for extracting data from websites, performing data mining tasks, and automating web scraping workflows in Python applications. # References ```dataview Table title as Title, authors as Authors where contains(subject, "beautifulsoup") or contains(title, "beautifulsoup") ```
