What is XML Nanny?
XML Nanny is a developer tool that allows you to validate XML and XHTML documents locally or over the web. It checks for XML well-formedness errors and XML validation errors with support for many popular schema validation types. It also supports Schematron 1.5 and provides verbose parsing mode. Each XML Nanny window is a Mac OS X "Document" which may be saved as a ".xmlnanny" file and reopened later. It also supports XML catalog and all parsing and validation is done using libxml2 except for Schematron.
1. • 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.
2. • Double-clicking errors in XML Nanny's results list UI opens the source document in your preferred Text Editor (this can be set in the Preferences Window).
3. Validate XML documents against Schematron schemas with assertions, reports, pattern tests, and diagnostic information reported through the XML Nanny UI.
4. Validation errors are reported in an attractive graphical list.
5. Mime-type and encoding values sent to XML Nanny from a web server via HTTP headers are now reported.
6. • All Parsing and Validation is done libxml2 except for Schematron, which is partially handled by the Schematron 1.5 XSLT reference implementation.
7. • Each XML Nanny window is a Mac OS X "Document" which may be saved as a ".xmlnanny" file and reopened later.
8. In the window that appears you can specify local custom DTDs via PUBLIC or SYSTEM identifiers.
