The World Wide Web Consortium's Extensible Stylesheet Language Transformations (XSLT) is a language for transforming XML documents so they can be processed by web browsers, databases, mobile phones, printers, XML processors, voice response systems, and LDAP directories. XSLT allows users to take their XML data when and where they want it. XSLT includes practical, real-world examples, which show how to apply XSLT stylesheets to XML data. The resulting transformations run the gamut of XML applications including sound files, HTML, WML, graphics (SVG), and Braille. Readers get a thorough understanding of XSLT and XPath and their relationship to other web standards, along with recommendations for a honed toolkit in an open platform-neutral, standards-based environment.
