Query: Who said bad things are cheap?

Its not enough being a very bad reference it is also veryexpensive (...)This book should not be allowed to be printed it is simply a hoax. Pages and pages spent with long examples containing long listings of useless data (like the USA baseball league examples) Those lists are spread all over the book, and if put together would consume more than a 100 pages of this book. The subject "XML" and its applications are approached slowly and superficially with POOR examples, the reading becomes uninteresting and fastidious. If one wants to waste money is better to through his bucks in the garbage! This book I wouldn't recommend for an enemy.
