AngleSharp
AngleSharp est un parser HTML5 DOM et un framework de web scraping conçu pour parser des documents HTML5, SVG et MathML en un modèle d'objet de document (DOM) conforme au W3C. Il fonctionne comme un générateur HTML programmatique et un moteur de sélecteur CSS pour interroger et localiser des éléments spécifiques au sein d'un DOM.
Le projet fournit des outils pour simuler des environnements de navigateur afin d'automatiser les interactions web, naviguer vers des URLs et soumettre des formulaires. Il inclut un minificateur HTML et CSS dédié pour réduire la taille des fichiers des ressources web en supprimant les caractères inutiles.
La bibliothèque prend en charge la manipulation du DOM HTML et l'extraction de données structurées à partir de sites web. Elle gère la transformation du balisage via un pipeline de parsing qui inclut une récupération d'erreurs pilotée par les spécifications et une construction de document hiérarchique.
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.
