Regarding the code examples, the explanations hardly illuminate the API.
The code stands as is; and the commentary does only a somewhat decent job
of explaining the larger context. You could always check the documentation
given in the back of the book, but that's hardly as helpful as a good overview
and commentary.

Moreover, and in some ways worse, I have found many typos -- and I am only
as far as the first two examples. These mistakes include missing import
statements, errant capitalization, bad indentation, double underscores ('__')
written as one long underscore. This is unacceptable. I can only hope it is just
this one chapter.

I bought this book because of the topics, and because I figured Python would
be the easiest way to learn XML API's. I am only hoping that the book will
get better, and that I will be able to derive benefit from it. As it stands,
I'm skeptical that I will get my money's worth.
