Validator

Much has been made of standards compliance in modern Web browsers. Less is made of the responsibity Web authors have to deliver correct mark-up for these programs, though only valid mark-up is eligible for standards-compliant processing. Typical validation tools tediously operate on one file at a time, often through a Web or editor interface. Validator easily checks one file or a thousand. It efficiently assures all your XML is ready for your workflow.

Features

Validator includes the following features:

• Drag-and-drop interface.
• Terse, text-based validation report.
• Validates common XML files without need for an Internet connection.
• Native support for DocBook, DITA, TEI, SMIL, MathML, SVG, WAP/WML, and more.
• Provides several XHTML correctness checks beyond simple validation.
• Optional command-line interface.
• Automatically skips non-XML files.
• Simple "delete it and it's gone" uninstall.
• Drag-and-drop installation on Mac OS X.

Benefits

Validator provides the following benefits:

• Works the way you work. Put the Validator icon on your Desktop or anywhere that's convenient.
• Can check thousands of files with a single drag-and-drop action or command-line statement.
• At-a-glance report quickly shows you if you have any XML errors, as well as where and what they are.
• Validation reports are easy to include in other documents, such as mail messages.
• Can validate XML files before your source-control system commits them to your repository. For example, Validator easily integrates into a CVS commitinfo script or a Subversion pre-commit hook.
• Integrates with other XML tools to simplify your XML workflow.
