W3C unveils new Markup Validator 11:33AM, Thursday 9th August 2007

W3C has overhauled its most popular service, the Markup Validator. The online tools that verifies websites' compliance with web standards has a new user interface and a validation engine with improved accuracy and performance.

Among new features are checking of HTML fragments and an automatic cleanup option using HTML Tidy, an open source tool that fixes markup errors and reorganises HTML code into an easy-to-read structure.

Run by W3C as an open-source software project, the markup validator aims to be a major step in any Web development quality process. To that end the new version adds support for SMIL 2.1 and XHTML Basic 1.1 as well as extended support for XML documents.

But most of the changes are under the hood, where the new architecture is faster and more reliable and will scale better as usage of the validator increases.

The W3C Markup Validator validates at validator.w3.org. Similar tools are available for checking RSS and Atom feeds, CSS stylesheets and hyperlinks.
