What is this book about?

Beginning XML, 3rd Edition, like the first two editions, begins with a broad overview of the technology and then focuses on specific facets of the various specifications for the reader. This book teaches you all you need to know about XML: what it is, how it works, what technologies surround it, and how it can best be used in a variety of situations, from simple data transfer to using XML in your Web pages. It builds on the strengths of the first and second editions, and provides new material to reflect the changes in the XML landscape — notably RSS and SVG.
