AngleSharp
AngleSharp ist ein HTML5-DOM-Parser und Web-Scraping-Framework, das entwickelt wurde, um HTML5-, SVG- und MathML-Dokumente in ein W3C-konformes Document Object Model zu parsen. Es fungiert als programmatischer HTML-Generator und CSS-Selektor-Engine zum Abfragen und Lokalisieren spezifischer Elemente innerhalb eines DOM.
Das Projekt bietet Tools zur Simulation von Browserumgebungen, um Web-Interaktionen zu automatisieren, URLs zu navigieren und Formulare abzusenden. Es enthält einen dedizierten HTML- und CSS-Minifier, um die Dateigröße von Web-Assets durch Entfernen unnötiger Zeichen zu reduzieren.
Die Bibliothek unterstützt HTML-DOM-Manipulation und die Extraktion strukturierter Daten von Websites. Sie handhabt die Transformation von Markup durch eine Parsing-Pipeline, die spezifikationsgesteuerte Fehlerbehebung und hierarchische Dokumentenkonstruktion umfasst.
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.
- Simulated Browser Environments - HTTP and HTML parsing library for .NET.
