AngleSharp
AngleSharp is an HTML5 DOM parser and web scraping framework designed to parse HTML5, SVG, and MathML documents into a W3C compliant document object model. It functions as a programmatic HTML generator and a CSS selector engine for querying and locating specific elements within a DOM.
The project provides tools for simulating browser environments to automate web interactions, navigate URLs, and submit forms. It includes a dedicated HTML and CSS minifier to reduce the file size of web assets by removing unnecessary characters.
The library supports HTML DOM manipulation and the extraction of structured data from websites. It handles the transformation of markup through a parsing pipeline that includes spec-driven error recovery and hierarchical document construction.
Features
- HTML and XML Parsing - Parses HTML5, SVG, and MathML documents into a standards-compliant DOM using spec-driven rules.
- W3C Compliant Parsers - Parses HTML5, SVG, and MathML documents into a W3C compliant document object model.
- HTML5 Parsers - Converts raw HTML5, SVG, and MathML markup into a standards-compliant document object model.
- HTML Tokenization - Converts raw HTML markup into a stream of tokens using a finite state machine before tree assembly.
- DOM Tree Traversers - Provides algorithms for walking through HTML DOM hierarchies using familial pointers to locate nodes.
- CSS Selector Engines - Implements a CSS-style selector engine for querying and locating specific nodes within the document object model.
- Structural Navigation - Implements structural navigation of document hierarchies using parent, child, and sibling node relationships.
- DOM Tree Construction - Transforms a token stream into a hierarchical Document Object Model with parent, child, and sibling pointers.
- DOM Element Selectors - Locates specific elements within a document using CSS selectors and standard DOM APIs.
- Dynamic HTML Generators - Programmatically creates and structures HTML elements to generate dynamic web content.
- HTML DOM Manipulators - Provides libraries for navigating and programmatically modifying elements within a parsed HTML document tree.
- Programmatic HTML Generators - Enables the programmatic generation of structured HTML documents for custom view engines.
- Web Automation and Scraping - Simulates a browser environment to automate web interactions, navigate URLs, and submit forms.
- Web Scraping and Extraction - Enables the extraction of structured data from websites through HTML parsing and CSS selectors.
- Web Scraping Frameworks - Provides a comprehensive framework for automating web interactions and extracting data from pages.
- Web Minification - Optimizes web assets by minifying HTML and CSS to improve page load speeds.
- Code Minifiers - Reduces the file size of HTML and CSS source code by removing unnecessary characters.
- Browser-Based Workflows - Provides a browser-like environment to automate interactions, navigate URLs, and submit forms programmatically.
- Markup State Machines - Converts raw markup into a stream of tokens using a predefined state-machine transition model.
- Two-Stage Parsing - Separates the initial tokenization of the input stream from the subsequent hierarchical DOM assembly.
- Spec-Driven Recovery - Automatically fixes malformed markup by applying specification-driven correction rules to ensure a valid DOM tree.
- General Utilities - HTML, CSS, and SVG parsing library.
- HTML and CSS Tools - HTML5 DOM and CSS3 OM construction library.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
