This edition offers developers a comprehensive guide to the rapidly evolving XML space. Topics covered range from fundamental syntax rules, to details of DTD and XML Schema creation, to XSLT transformations, to APIs used for processing XML documents. Whether you're a Web designer using SVG to add vector graphics to Web pages, or a C++ programmer using SOAP to seria lize objects into a remote database, XML in a Nutshell explains the basic rules that all XML documents - and all XML document creators - must adhere to, including: essentials of the core XML standards; key technologies used mainly for narrative XML documents such as Web pages; technologies for building data-intensive XML applications, and for processing XML documents of any kind. The book should help the reader understand the tools and APIs needed to write software that processes XML, including the event-based Simple API for XML (SAX2) and the tree-oriented Document Object Model (DOM). Quick-reference chapters also detail syntax rules and usage examples for the core XML technologies, including XML, DTDs, Xpath, XSLT, SAX, and DOM.
