Htmlparser2 - parse HTML and XML efficiently

Features

HTML and XML Parsing - High-performance library for extracting and processing data from HTML and XML markup documents.
DOM Tree Construction - Converts markup strings into a structured object tree with support for XML mode and character indices.
DOM Manipulation - Provides a suite of tools for parsing and programmatically manipulating HTML/DOM in server-side environments.
Streaming Parsers - Implements a memory-efficient parser that processes large markup documents incrementally.
XML and HTML Document Parsers - Fast and forgiving parser that converts HTML and XML content into in-memory document trees.
State-Machine Parsers - Uses a state-machine based approach to convert input streams into tokens for complex HTML and XML syntax.
Stream-Based Text Processing - Consumes markup data incrementally through a writable interface to process large documents without full memory loading.
DOM Tree Construction - Transforms a sequence of parsed tokens into a hierarchical Document Object Model for programmatic use.
Node Querying - Provides tools for searching parsed document trees using IDs, tags, and custom filters to retrieve content.
DOM Manipulation Libraries - Ships a comprehensive toolset for selecting, modifying, and serializing document object model trees.
DOM Serialization - Converts a modified structured document object model back into an HTML or XML string.
Incremental Parsing - Offers incremental parsing of documents using callbacks to process data in chunks.
Stream-Based Parsing - Provides event-driven parsing for large XML and HTML files to minimize memory consumption.
Feed Parsing Libraries - Provides a library for decoding and processing various web feed formats like RSS, RDF, and Atom.
Large Scale XML Processing - Processes massive markup files using streaming and callbacks to avoid high memory usage.
Syndication Feed Parsers - Extracts structured metadata and entries from RSS, RDF, and Atom syndication feeds.
Event-Driven Callbacks - Implements a callback-driven mechanism that triggers events upon encountering specific markup tokens.
Web Scraping - Provides the parsing foundations for extracting structured data from websites and web feeds.
Parsing Tools - HTML and XML parser.
