SwiftSoup
SwiftSoup es una biblioteca de procesamiento HTML multiplataforma para Swift que convierte cadenas y archivos HTML o XML sin procesar en un modelo de objetos de documento (DOM) estructurado. Proporciona la infraestructura central para analizar contenido web en un árbol navegable, permitiendo el acceso programático a elementos de página en iOS, macOS y Linux.
La biblioteca cuenta con un motor de selectores CSS para la extracción de datos y un sistema de sanitización basado en listas blancas para eliminar etiquetas y atributos inseguros del contenido enviado por el usuario. Optimiza las consultas de documentos repetitivas mediante el almacenamiento en caché de consultas memorizadas.
El proyecto cubre la manipulación del DOM para actualizar elementos y atributos, recorrido recursivo del árbol para búsquedas profundas y análisis basado en tokens para transformar el marcado en datos estructurados.
Features
- HTML and XML Parsing - Converts HTML and XML from URLs, files, or strings into a structured tree with automatic format detection.
- HTML Tokenization - Converts raw HTML strings into a structured document object model using a token-based parsing process.
- XML and HTML Document Parsers - Parses HTML and XML content from strings or files into in-memory document trees for programmatic access.
- HTML Content Sanitization - Filters HTML content using a whitelist to strip unsafe tags and attributes and prevent XSS attacks.
- CSS Selector Engines - Implements a CSS-style selector engine for querying and filtering HTML and XML document structures.
- CSS Selector Data Extractors - Extracts precise content from pages by evaluating CSS selectors, tags, IDs, and classes against the DOM.
- DOM Tree Construction - Transforms token streams into a hierarchical Document Object Model representation for HTML and XML.
- Element Modifications - Enables dynamic updating of HTML documents by modifying elements, attributes, and text.
- HTML DOM Manipulators - Offers tools for navigating, filtering, and modifying elements within a parsed HTML document tree.
- Web Scraping and Extraction - Extracts structured data from websites using CSS selectors and DOM traversal in a Swift environment.
- Selector Result Caching - Stores parsed selector evaluations to speed up repetitive document queries and reduce processing overhead.
- Memoization Caches - Provides memoization caches to store expensive selector evaluations and optimize repetitive document lookups.
- Recursive Tree Traversers - Navigates the document hierarchy using recursive patterns for deep searches and structural modifications.
- Cross-Platform HTML Processing - Provides a consistent Swift-based library for parsing and managing web content across iOS, macOS, and Linux.
- HTML Parsing - Parses HTML using DOM, CSS, and jQuery-like selectors.
