XSLT (Extensible Stylesheet Language Transformations) is a powerful tool for transforming XML to other formats, such as HTML and PDF. It is at the heart of most XML applications and is a notoriously difficult language to understand. Mastering XSLT offers experienced XML developers comprehensive how-to information, plus an in-depth XSLT reference, including XPath. The book has a special emphasis on converting XML to HTML, a major application of XSLT. A entire section of the book focuses on specific implementation issues, including dealing with different kinds of non-XML output, such as special characters and math computations.
