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 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.
I'm not actually a beginner with XML. I've used it (and some of the related technologies a little bit). So I'd learned bits and pieces but never had a formal overview. This book helped me fill in some of the wholes, understand the relationship between similar technologies (like DTD and XSL). The writing and formatting aren't anything special, and it's a beginner book in that it had lots of breadth but limited depth. The examples were interesting enough, though they often felt redundant or unnecessary. I'd recommend it if you're like me and need enough of an overview of the landscape to get going.
