This book is for intermediate to advanced ASP programmers, who have little or no knowledge of XML, and want to expand their programming ability by adding XML skills to their repertoire. XML will be explained from the ground up. However, other technologies will not be discussed in such detail and it is assumed that the user is familiar with other Internet techniques on the Microsoft platform, such as (D)HTML, client-side scripting with JScript, and programming in Visual Basic. You should have at least a basic understanding of three-tier architectures like Microsoft DNA. If you have read or heard a bit about XML and wonder how to use it best, building on your existing programming skills, then this book is for you.
