HtmlUnit Reviews

jsoup is a Java library that streamlines the process of working with HTML and XML in real-world applications. It provides a user-friendly API for fetching URLs, parsing data, extracting information, and manipulating it through DOM API methods, CSS selectors, and XPath queries. By adhering to the WHATWG HTML5 specification, jsoup ensures that the HTML it parses is transformed into a DOM structure comparable to that used by modern web browsers. This library enables users to scrape and parse HTML from various sources, such as URLs, files, or strings; locate and extract information using DOM traversal or CSS selectors; modify HTML elements, attributes, and text; and sanitize user-generated content to safeguard against XSS vulnerabilities while producing clean HTML output. jsoup is adept at handling the diverse spectrum of HTML encountered online, ranging from well-formed and valid to messy, non-compliant tag-soup, resulting in a coherent parse tree. For instance, one can retrieve the homepage of Wikipedia, parse it into a DOM structure, and extract the headlines featured in the "In the news" section, organizing them into a list of elements for further use. This flexibility makes jsoup an invaluable tool for developers who need to interact with web content efficiently.
