I must be missing something but I don't understand why is there no module that would provide the W3C validation without hitting http://validator.w3.org and without the need to setup a similar web site?
WWW::CheckSite::Validator uses that web site WebService::Validator::HTML::W3C provides an interface to the W3C web site. Did I miss the module or is there some difficulty in creating such module, something I don't see? As an alternative, is there a downloadable and free command line tool that would do this job ? Gabor
