Extensible Stylesheet Language

FO Test Suite

FO Tips & Tricks

XSL is a language for specifying stylesheets. Given a class of arbitrarily structured XML documents or data files, designers use an XSL stylesheet to express their intentions about how that structured content should be presented; that is, how the source content should be laid out and paginated onto some presentation medium, such as a window in a Web browser or a hand-held device, or a set of physical pages in a catalog, report, pamphlet or book.


An introduction to XSL Formatting Objects

This book is intended to address the needs of someone looking for an introduction to the Extensible Stylesheet Language(XSL) as specified by the World Wide Web Consortium at Specifically the XSL FO (XSLFO) aspect of XSL, an XML vocabulary targeted at expressing stylesheets which rigorously express how source content should be laid out and paginated for presentation.


DocBook XSL Stylesheets

Demo: Books in DocBook

DocBook is a document type definition (DTD) available in both SGML and XML. It is particularly well suited to books and papers about computer hardware and software (though it is by no means limited to these applications). XSL stylesheets transform valid DocBook documents into several formats, including XSL FO (XSLFO), which is used to produce quality printed output.
