XSL Developer's Guide

---

The World Wide Web Consortium (W3C ) Working Draft for XSL divides the language into two main parts: a transformation language for XML documents, and an XML vocabulary for formatting semantics. Microsoft® Internet Explorer 5 supports a subset of the transformation part of the Extensible Stylesheet Language (December 18th Working Draft) . Microsoft plans to update this technology to match the final W3C recommendation for XSL. XSL Working Draft Conformance Notes details the differences between the Internet Explorer 5 implementation and the December draft.

XSL transformations address some common needs in XML:

• Enabling display: The XSL transformation language enables display of XML by transforming XML into grammar and structure suitable for display—for instance, into HTML or the XSL Formatting Objects language.
• Direct browsing of XML files: Internet Explorer 5 can apply XSL style sheets that produce HTML, allowing direct browsing of the XML files.
• Content delivery to downlevel browsers: XSL transformations can be executed on the server to provide HTML documents for downlevel browsers.
• Schema Translation: The transformation process is independent of any particular output grammar and can be used for translating XML data from one schema to another.
• Converting XML through querying, sorting, and filtering: The transformation can be used for general-purpose transformations within a single grammar, including filtering, sorting, and summarizing data.
