BeautifulSoup is a Python library for pulling data out of HTML and XML files. It creates a parse tree for parsed pages that can be used to extract data from HTML, which is useful for web scraping.

This project is a Python script that uses BeautifulSoup4 to scrape and parse web pages. It can extract data from HTML and XML documents .So I have used IPL_Auction 2023 ,flipkart product page and Bangalore Hotel Booking to extract the tabel , reviews etc.

To run this project, you need to have Python 3 and BeautifulSoup4 installed on your system. You can install BeautifulSoup4 using pip:

pip install beautifulsoup4

You also need to have requests or urllib installed to fetch web pages. You can install requests using pip:

pip install requests

The official documentation of BeautifulSoup4 can be found here:

Some frequently asked questions about this project are:

• How do I specify a parser?

• You can pass the name of the parser as the second argument to the BeautifulSoup constructor. For example: soup = BeautifulSoup(html, "lxml"). If you don't specify a parser, BeautifulSoup will use the best one available on your system.

• How do I navigate the parse tree?

• You can use various methods and attributes to access different elements and attributes of the parse tree. For example: soup.title returns the <title> tag, soup.find("p") returns the first

  tag, soup.find_all("a") returns a list of all tags, etc. You can also use CSS selectors or regular expressions to find elements that match certain criteria.

• How do I modify the parse tree?

• You can use methods like append, insert, replace_with, extract, etc. to add, remove, or replace elements in the parse tree. You can also modify the attributes and contents of elements using assignment operators. For example: link["href"] = "https://new.url" changes the href attribute of a link element, tag.string = "New text" changes the text content of a tag element, etc.

• Q: How can I change the output format?

• A: You can modify the save_data function in the script to save the data in different formats, such as CSV, JSON, or SQL.

• Q: How can I handle errors and exceptions?

• A: You can use try-except blocks to catch and handle errors and exceptions that may occur while scraping or parsing web pages.

• Q: How can I scrape dynamic web pages that use JavaScript?

• A: You can use Selenium or other tools that can render JavaScript and interact with web elements.
