XSLT Cookbook

Sal Mangano has been developing software for over 12 years and has worked on many mission critical applications, especially in the area of financial trading applications. Unlike many XML/XSLT developers, he did not approach the technology from the standpoint of the Internet and web development but rather from the broader need for a general-purpose data transformation framework. This experience has given him a unique perspective that has influenced many of the recipes in this book. Sal has a master's degree in computer science from Polytechnic University.
