Beautiful Soup

Beautiful Soup is a Python library (currently version 4.x) that provides Pythonic tools for navigating, searching, and modifying parsed HTML and XML documents.

Beautiful Soup is the essential Python package for turning raw, messy web content into a structured, navigable tree: it efficiently parses HTML or XML, even if the markup is poorly formed (known as 'tag soup'). It sits atop a parser (like `lxml` or `html.parser`), offering intuitive methods such as `find()` and `find_all()` to locate specific elements based on tags, attributes (e.g., `class='product-name'`), or text strings. This capability makes it a foundational tool for web scraping, allowing developers to quickly extract targeted data points like links (`<a>` tags) or paragraph text (`<p>` tags) from a document object model (DOM) structure.
