Table of contents About this service Other resources Credits About this service The Markup Validator is a free service by W3C that helps check the validity of Web documents. Most Web documents are written using markup languages, such as HTML or XHTML. These languages are defined by technical specifications, which usually include a machine-readable formal grammar (and vocabulary). The act of checking a document against these constraints is called validation, and this is what the Markup Validator does. Validating Web documents is an important step which can dramatically help improving and ensuring their quality, and it can save a lot of time and money (read more on why validating matters). Validation is, however, neither a full quality check, nor is it strictly equivalent to checking for conformance to the specification. This validator can process documents written in most markup languages. Supported document types include the HTML (through HTML 4.01) and XHTML (1.0 and 1.1) family, MathML, SMIL and SVG (1.0 and 1.1, including the mobile profiles). The Markup Validator can also validate Web documents written with an SGML or XML DTD, provided they use a proper document type declaration. This validator is also An HTML validating system conforming to International Standard ISO/IEC 15445—HyperText Markup Language, and International Standard ISO 8879—Standard Generalized Markup Language (SGML) – which basically means that in addition to W3C recommendations, it can validate according to these ISO standards. Related resources include: The Documentation for the Markup validation contains a lot of information on usage, installation, and development. Notably, the Help and FAQ document contains a lot of information, and is a recommended reading. The Source code availability information page . The development roadmap for this service. How to provide feedback on The W3C Markup Validation Service. Other resources Online Tools & Other Validators In addition to this validator, the W3C is offering a number of other tools to help you check other types of documents (CSS, RDF, P3P, ...), find broken links in your Web pages, and so on. All these tools are listed on the W3C's QA Toolbox. There are also many excellent tools developed outside W3C to help improve the quality of Web pages: HTML tidy, originally developed at W3C, is a program that can help automatically clean up HTML pages. Validome offers a very reliable validator for HTML, XHTML and WML, in different languages. The WDG HTML validator is another excellent online validation service. A Real Validator is a shareware HTML syntax checker for Windows systems, from the author of the WDG validator.
