Query: Perfectly Unstructured Writing

I bought this book a while ago and thought that I would read it at leisure but the way the authors dive into topics without presenting a rational explanation is simply absurd. Even the contrast between XML and HTML on page 6 is wonderfully blurry. The book appears structured but revels in throwing coding examples at you without a premise. I know and practice both XHTML and CSS but this book made XML seem like rocket science, which it is not. Please do not buy this book and waste your money.
