Essential XML Quick Reference , by Aaron Skonnard and Martin Gudgin (Boston, MA: Addison-Wesley, 2002). I don't directly recommend very many other books in this book, but this is one I suggest without reservation. If you deal with XML on any technical basis at all, this book needs to be in your collection.
