ineed - Web scraping and HTML-reprocessing. The easy way.

•    Javascript

Web scraping and HTML-reprocessing. The easy way.ineed doesn't build and traverse DOM-tree, it operates on sequence of HTML tokens instead.

html5ever - High-performance browser-grade HTML5 parser

•    Rust

html5ever is an HTML parser developed as part of the Servo project. It can parse and serialize HTML according to the WHATWG specs (aka "HTML5"). There are some omissions at present, most of which are documented in the bug tracker. html5ever passes all tokenizer tests from html5lib-tests, and most tree builder tests outside of the unimplemented features. The goal is to pass all html5lib tests, and also provide all hooks needed by a production web browser, e.g. document.write.

AngleSharp - The ultimate angle brackets parser library parsing HTML5, MathML, SVG and CSS to construct a DOM based on the official W3C specifications

•    CSharp

AngleSharp is a .NET library that gives you the ability to parse angle bracket based hyper-texts like HTML, SVG, and MathML. XML without validation is also supported by the library. An important aspect of AngleSharp is that CSS can also be parsed. The included parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code and ensures compatibility with results in evergreen browsers. Also standard DOM features such as querySelector or querySelectorAll work for tree traversal.
