Validator

Validator Publisher's Description:
Much has been made about standards compliance in modern Web browsers. Less is made about the responsibity Web authors have to deliver correct mark-up to these programs. Some HTML authors champion one browser over another for its standards support when they themselves do little or nothing to assure their mark-up is correct. Unfortunately, most validation tools operate on one file at a time through a Web or editor interface. This makes checking large numbers of files in a production environment tedious and impractical. Validator easily checks one file or a thousand. It efficiently assures all your XML is ready for your workflow.
