Title: Avoid this one
Review: This is the worst XML documentation I've run across, online or on paper. I am not a total beginner with XML, I didn't expect this book to be a tutorial, and I picked up this book because it seemed like it would get to the point quickly. At first it seemed promising because of its brevity; then I realized that it was written very sloppily. In the Overview (chapter 1), the first mention of a DTD (with no explanation of what it's an abbreviation of), states "XML supports but does not require DTDs". Great. Good thing I knew what a DTD was, because this book wasn't going to tell me. Four pages later, the book tells me, "As you have already learned, a DTD defines rules for document contents." Well, I sure didn't "already learn" it from this book! Amazing that it references prior material that it doesn't contain! The rest of the book is more of the same. Very poor.
Is the review positive or negative?
