The type-awareand schema-aware features of XSLT 2.0 can greatly assist you when you debug a stylesheet, and improve stylesheetquality and robustness in handling all input data. Learn how to use type-aware and schema-aware XSLT 2.0 during the debugging and testing processto avoid common issueswith invalid paths, incorrect assumptionsabout data types, and cardinalities. Also, find examplesof XSLT stylesheets that contain errors that would notbe caughtifschema-aware featureswerenotin use, and discover how explicitly specifying types results in useful error messages.
The Gang ofFour’sInterpreter design pattern encourages extending a languageby building a new language from it. Most functional languages letyou extend the languagein a variety of ways, such as operator overloading and pattern matching. Although Java™ doesn’t permitanyofthesetechniques, next-generation JVM languages do, with varying implementation details. In this article, Neal Ford investigateshow Groovy, Scala, and Clojure realizethe intent of the Interpreter design pattern byallowing functional extensions in ways thatJava does not.
