I am working on a project where I have to validate the complete site, which has around 150 pages, through W3C Markup Validation. Is there a way to check W3C Markup Validation of an entire website?
The W3C doesn't offer this on w3.org.
http://validator.w3.org/docs/help.html#faq-batchvalidation
But you can use this tool and check "Validate entire site": (Also w3.org refers to this site!)
But you have a limit of 100 URLs to validate and will get this message when you reach 100 URLs:
Batch validation is limited to 100 URLs at one time. The remaining URLs were not checked.
Also there's a limit of errors displayed for each url.
