Book: XSLT Cookbook
The XSLT Cookbook is a collection of hundreds of solutions to problems that Extensible Stylesheet Language Transformations (XSLT) developers regularly face. The recipes range from simple string-manipulation and mathematical processing to more complex topics like extending XSLT, testing and debugging XSLT stylesheets, and graphics creation with SVG. Among the variety of XSLT books now available, none has the explicit solution-oriented approach of this Cookbook.
Extensible Stylesheet Language Transformations (XSLT) is a powerful technology for transforming XML documents into other useful forms, but it is sometimes considered difficult to learn. Its template-based approach makes it a prime candidate for learning by example, and XSLT examples are often easily repurposed.
When I first began working with XSLT, I longed for a cookbook that would accelerate my productivity by providing ready-made solutions to the challenges I faced. My first experience with such a book was O’Reilly’s Perl Cookbook. This book was more influential to my reluctant learning and ultimate appreciation of Perl than the original camel book (Programming Perl) by Larry Wall. I believe cookbooks are important because most software developers are not satisfied with simply figuring out how to make something work: they are interested in mastering the technology and using the best-known techniques, and they want answers fast. There is no better way to master a subject than by borrowing from those who already discovered better ways to do things.
Longing for a cookbook soon turned into a desire to write one, especially since I collected several useful recipes—some that were developed by others and some that I created. However, I did not want to write an XSLT book simply packaged in an alternate form; I wanted to provide a useful resource that also highlighted some less-obvious ways to apply XSLT. In the process, I hoped to attract XML developers who have not yet been motivated to learn XSLT and who, in my opinion, are missing out on one of XML’s best productivity tools. If you are one of these folks who has not yet experienced XSLT, please bear with me for a few more paragraphs while I pitch the value of XSLT and the role of this book in helping you realize its potential.
XSLT is a language that lives simultaneously on the fringes and in the mainstream of current software-development technology. While working on this project, I often found myself explaining to friends what XSLT was and why it was important enough to spend time writing a whole book about it. These same friends have heard of Java, Perl, and even XML, but not XSLT. I also observed an increasing number of requests for XSLT assistance on XSLT mailing lists and more industry attention in the form of books, articles, and sophisticated XSLT development tools. The XSLT user base is clearly growing daily; however, many software professionals and technology enthusiasts do not understand what it is and why it is important.
