Erik Siegel’s new book, Schematron: A Language for Validating XML, is now available from Amazon.com, Barnes and Noble, and many other online retailers.
Schematron is a validation language that checks XML documents against business rules. It extends the validation provided by languages such as Document Type Definitions (DTD), W3C XML Schema, and RELAX NG, giving you the ability to check your XML documents for compliance with rules that can be difficult, if not impossible, to check with the other validation languages.
Schematron: A Language for Validating XML explains the language in detail and contains many examples to highlight its features. Anyone who uses Schematron or would like to begin using it will find a wealth of information.
