Parse5
parse5 est un parseur et sérialiseur HTML WHATWG pour Node.js. Il transforme les chaînes HTML en un modèle objet de document (DOM) et reconvertit ces arbres en chaînes HTML valides, en suivant la logique définie par le standard HTML Living Standard.
Le projet fonctionne comme un processeur HTML en flux, utilisant une analyse incrémentale pour traiter les documents volumineux par blocs. Il inclut un tokenizer conforme à HTML5 qui utilise une approche par machine à états pour diviser l'entrée en jetons selon les spécifications web officielles.
L'ensemble d'outils couvre l'analyse de documents HTML, la sérialisation et la réécriture en temps réel via des flux. Ces capacités permettent l'analyse programmatique et l'extraction de données à partir de documents HTML tout en maintenant une cohérence entre différents environnements.
Features
- XML and HTML Document Parsers - Parses HTML5 content from strings or files into in-memory document trees for traversal and manipulation.
- WHATWG HTML Standard Implementations - Implements the exact parsing and serialization logic defined by the HTML Living Standard for cross-browser consistency.
- Incremental Parsing - Processes large HTML documents in small chunks via incremental parsing to minimize memory consumption.
- HTML - Provides incremental parsing of HTML documents via streams to handle large files without loading the entire source into memory.
- HTML Serialization - Converts structured document object model trees back into valid HTML text strings.
- HTML Tokenization - Implements a state-machine driven tokenizer that converts character streams into HTML tokens according to web specifications.
- State-Based Parsing - Implements state-machine driven parsing to track context and handle incoming characters according to HTML standards.
- DOM Tree Construction - Transforms a sequence of tokens into a hierarchical document object model using specific nesting and stacking rules.
- DOM Serialization - Transforms a structured document object model back into an HTML string for output or storage.
- HTML and XML Serialization - Provides the complete pipeline of parsing HTML into a tree and serializing that tree back into HTML strings.
- HTML String Parsing - Converts HTML strings into a structured tree representation for programmatic analysis of document content.
- HTML Living Standard Compliance - Ensures parsing and serialization behave consistently by following the official WHATWG HTML Living Standard.
- HTML Parsers - Provides a complete toolset for parsing and serializing HTML strings into a document object model following WHATWG standards.
- Large Scale Streaming - Enables parsing and rewriting of massive HTML files using streams to prevent system memory overload.
- HTML Response Rewriting - Modifies HTML content during the streaming process to perform real-time transformations of the document structure.
- Incremental HTML Processing - Processes large HTML documents in chunks to minimize memory usage during analysis and real-time rewriting.
- Parsing Tools - HTML parsing and serialization.
- Parsing Utilities - Spec-compliant HTML parser.
