HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as xhtml.
Elements that have the xml:lang attribute also need a matching lang attribute. In HTML5 documents, using just the lang attribute is enough.
6,250 HTML checks per week. Fully automated.
Save time using our automated web checker. Let our crawler check your web pages on the W3C Validator.
