W elcome to Beginning XSLT 2.0, a comprehensive introduction to the Extensible Stylesheet Language: Transformations 2.0. This book introduces you to transforming XML with XSLT 2.0, helping you to create tailored presentations for all the information you have accessible as XML. I wrote this book, like Beginning XSLT, based on my own experience as an XSLT user, but also based on my familiarity, from training people in XSLT, with the practical and conceptual hurdles that newcomers often face. My aim is to provide a step-by-step, how-to manual for the kind of the real-world transformation problems that you will come across. Who This Book Is For This book is primarily for newcomers to XML and XSLT. It's particularly aimed towards web developers who have some knowledge of HTML, CSS, and a smattering of JavaScript; but none of these are essential, and the techniques you learn in this book can just as easily be applied to transforming between XML-based markup languages as to web pages. Seasoned users of XSLT 1.0 will learn about the new datatypes, expressions, and functions of XPath 2.0 and the new facilities in XSLT that make tasks such as text processing, grouping, and creating multiple documents much easier. Although much will look familiar, there are also some fundamental changes in the XPath data model and the XSLT processing model that may take you by surprise.

It's hard to believe now, but there was a time when writing jokes about multi-dispatch inheritance in dynamically typed languages simply wasn't the glamorous, highly paid profession that it is today. Before Slashdot, before User Friendly and the Joy of Tech, before Futurama, before Old Man Murray, before Dilbert, and before 1001 Surefire Gags about C++ That Will Wow Your Klingon Wedding Guests,  funny for geeks was a criminally underserved market sector. Biro-drawn cartoon strips were the typical fare, all called something like Just Byting Around! or Giga-giggles! These would run for a few months in Practical Computing or PC Handholder or some such ma- zine. After recycling gags revolving around hard drives and floppy disk entendres, these wretched specimens died for lack of inspiration and, I would hope, some vestigial sense of shame. And then there was, thank God, Verity Stob. I remember the first time I read the Stob column. It was 1988, and I was hiding in a fluorescent-lit dungeon in the heart of my university, strumming futilely through the lower-rent academic journals and controlled-circulation tech mags. The first few lines some throwaway comment about Lisp, I think had my snorts echoing across the library.

Rigor Without the Mortis Many people (especially agilists) associate a high-ceremony software development process with a dead project (i.e., rigor mortis), and this association is not entirely incorrect. Our approach aims to put back the rigor while le- ing out the mortis that is, we can do rigorous analysis and design without killing the project with an excessively high-ceremony approach. The goal of this book is to describe that process in full detail. Agility in theory is about moving ahead at speed, making lots of tiny course corrections as you go. The theory (and it's a good one) is that if you spend months or years producing dry specifications at the start of the project and then set them in concrete,  this doesn't necessarily (and in practice, doesn't) lead to a product that meets the c- tomer's requirements, delivered on time and with an acceptably low defect count. It's likely that the requirements will change over time, so we need to be prepared for that, and it's likely that a lot of the original requirements will turn out to be wrong or new requirements will be discovered after the requi- ments concrete  has set. Agile methods answer this problem in a number of different ways, but the overriding principle is to break things down into smaller chunks and not to go setting anything in concrete (least of all your requirements specs).

In the 1990s, Microsoft did the impossible and released a programming tool that let everyone write programs to run on Windows. Author Peter Wright was so excited about that tool, Visual Basic, that he wrote a series of books on it and introduced nearly a quarter of a million people all over the world to programming. Now Microsoft has done it again with the release of the Express tools. With nearly every home now having a computer and most people having access to the Internet, being able to take control of the computer and write your own programs is more useful and exciting than ever. So Wright has decided to do it again. In this book, you'll find everything you need to program your computer by using Visual C# 2005 Express, one of the very latest programming tools from Microsoft. If you have never written computer programs before, Wright will show you how much fun and how easy it can be. Perhaps you are a programmer and just need to get up to speed on .NET for work this book is for you too. Wright took the same approach with this book that he did with the VB titles, and inside you'll find a fast-paced guide to the essentials to get you programming fast. You'll learn the C# language and the tools Visual C# 2005 Express provides. He covers everything from simple console programs to code that talks to the Internet, and even how to write your own database programs. Whatever your reasons for wanting to learn to program with C#, this book will get you where you want to be quickly, and hopefully with a smile on your face. So dive in and change the way you use computers forever.
