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 parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code. Also current features such as querySelector or querySelectorAllwork for tree traversal.
