What it is and what it does
tree-sitter-html is a language grammar for the tree-sitter incremental parser, specifically targeting HTML. It translates HTML source code into a concrete syntax tree that can be traversed and analyzed programmatically. The package is a compiled extension (available as prebuilt wheels for multiple platforms) that integrates with the tree-sitter ecosystem to enable fast, incremental parsing of HTML documents.
Developers use this package when they need to parse HTML programmatically—extracting structure, analyzing document trees, or building tools that reason about HTML syntax. It's particularly useful for code editors, linters, static analysis tools, and any application that needs to understand HTML structure. The grammar is based on the HTML5 specification.
Use it for
- Extract and analyze HTML document structure for web scraping or content extraction tasks.
- Build linting or validation tools that check HTML syntax and structure.
- Implement syntax highlighting or code navigation in HTML editors.
- Generate abstract syntax trees for HTML transformation or code generation pipelines.
- Analyze HTML templates or markup in static site generators or documentation tools.
