Query: This is the one!

Having read Steven Holzner's Java Black Book, I ordered this XML book "sight unseen." This is the best XML book I've seen to date because it strikes the right balance between theory and application. Within just the first few pages, you have a good grasp what XML is, how it is used, and how YOU can actually use it. Too many other books seem to delve too deeply into XML anatomy or a specific application of XML, that the reader comes away with little understanding of what XML is and how it can be used, regardless of the specific environment.
