Jsoup is a popular Java library for parsing and manipulating HTML and XML documents. It provides a convenient and straightforward way to extract and manipulate data from web pages, making it a valuable tool for web scraping and data extraction tasks. Jsoup is often used by developers to automate the retrieval of information from websites.

Here are some key features and uses of Jsoup:

1. HTML Parsing: Jsoup allows you to parse HTML documents and extract data from them. It provides a simple and intuitive API for traversing the HTML document tree, selecting elements, and extracting content.

2. CSS Selectors: Jsoup supports CSS-style selector queries, which make it easy to locate and select specific elements within an HTML document. This is similar to the way you would select elements with CSS for styling.

4. Data Extraction: Jsoup is often used for web scraping tasks, where it allows you to extract data from web pages, such as news articles, product listings, or any other structured content.

5. Clean and Validate HTML: Jsoup can be used to clean and sanitize HTML documents by removing potentially unsafe or non-standard elements and attributes. It can also validate HTML to ensure it adheres to a specified schema.

6. Compatibility: Jsoup is compatible with Java 7 and later versions, making it suitable for a wide range of Java applications.
