XML by Example teaches Web developers to make the most of XML with short, self-contained examples every step of the way. The book presumes knowledge of HTML, the Web, Web scripting, and covers such topics Document Type Definitions, Namespaces, Parser Debugging, XSL (Extensible Stylesheet Language), and DOM and SAX APIs. At the end, developers will review the concepts taught in the book by building a full, real-world e-commerce application.
