XML Nanny is a Developer Tool that allows you to Validate XML and XHTML documents locally or over the web.
FEATURES:
• Parse either local XML files or files on a web server using HTTP. In the "Source" text field specify either a local file path or an HTTP URL.
• Checks for XML Well-Formedness errors. Errors are reported in an attractive graphical list.
• Checks for XML Validation errors, with support for many popular Schema Validation types: DTD (internal or external), XML Schema (XSD), RELAX NG (XML syntax only), and Schematron. Validation errors are reported in an attractive graphical list.
• Schematron 1.5 Support. Validate XML documents against Schematron schemas with assertions, reports, pattern tests, and diagnostic information reported through the XML Nanny UI.
• Verbose Parsing mode provides more instance document/DTD details through the UI... kinda like a visual SAX parser.
• Each XML Nanny window is a Mac OS X "Document" which may be saved as a ".
