The automated creation of sophisticated print layouts and function-rich digital publications (E-PDF) and documentation from arbitrarily structured XML documents: this is what the XSL-FO technology offers. The basic part contains a compact introduction to the techniques of data transformation (XSLT) and data access (XPath), providing the necessary application know-how for beginners in the field. For experienced XSL-FO designers the application part contains a wealth of examples, even for complex document design. The English version of the original German publication has been carefully edited. Consistent and well thought-out design principles for stylesheets make their creation and maintenance easy to organize. The Antenna House XSL Formatter is the recommended formatter. Its extensions and special features are described in detail.
