XML in a Nutshell, 3rd Edition

What’s New in the Third Edition

XML has not stood still in the two years since the second edition of XML in a Nutshell was published. The single most obvious change is that this edition now covers XML 1.1. However, the genuine changes in XML 1.1 are not as large as a .1 version number increase would imply. In fact, if you don’t speak Mongolian, Burmese, Amharic, Cambodian, or a few other less common languages, there’s very little new material of interest in XML 1.1. In almost every way that practically matters, XML 1.0 and 1.1 are the same. Certainly there’s a lot less difference between XML 1.0 and XML 1.1 than there was between Java 1.0 and Java 1.1. Therefore, we will mostly discuss XML in this book as one unified thing, and only refer specifically to XML 1.1 on those rare occasions where the two versions are in fact different. Probably about 98% of this book applies equally well to both XML 1.0 and XML 1.1.

Elliotte is responsible for almost half of the early implementations of XInclude, as well as having written possibly the first book that used XInclude as an integral part of the production process, so it’s a subject of particular interest to us. Other chapters throughout the book have been rewritten to reflect the impact of XML 1.1 on their subject matter, as well as independent changes their technologies have undergone in the ...
