Automated XHTML source-code validation
Recently, I`ve found an idea of automation XHTML source-code validation. If there is a way of doing so, it will give us a possibility of writing valid semantic code regarding all W3C rules and reduce errors in Java scripts caused by some mistakes in semantics. It will reduce our time spend for manual checking for validation every page. It will gives us an an opportunity to find bugs almost in the real-time, not in the project-deploy period.
What do you think about this idea? I understand, that probably it`s not a unique idea, but anyway.. I want to know what do you think about it.
