HTML Tidy is a console application and C library (libtidy) that corrects and cleans up HTML and XML documents by fixing markup errors and upgrading legacy code to modern HTML5 standards. It can be used standalone or integrated into other applications via its thread-safe, easily wrapped C API.
Use cases
- fix mismatched, misnested, or missing HTML tags in a document
- clean up and validate legacy HTML and convert it to modern standards
- tidy XML and XHTML documents from the command line
- integrate HTML correction into a web server, editor, or scraper via libtidy
- check HTML markup errors in a CI pipeline
When to choose
- you need battle-tested HTML/XML cleanup and error correction
- you want a small C library to embed HTML tidying in another tool
- you work from the command line and want quick markup fixes
When to avoid
- you need a full HTML parser/DOM for programmatic manipulation rather than cleanup
- you need a browser-grade HTML5 parser with scripting support
- you want a pure-JavaScript or managed-language solution without C linkage
