Hunter does a good job explaining each item and I really like the way he branches into many related technologies, instead of just plain XML. Those related technologies include XSLT and XPath, DOM, SAX, DTDs and schemas. Some of these things, such as schemas and DTDs are essential for learning XML, so I'm glad they are covered.
At the beginning of the book, I thought that Hunter was another Microsoft lemming, just following the Microsoft trends and technologies. But it soon became apparent that he uses MS products where they make sense, but is quick to point out their drawbacks. It irks me to no end how the entire world chooses an internationally-accepted standard, then MS decides to come up with their own. Hunter does a good job of pointing that out.
One complaint is that this book doesn't do much in helping the Macintosh user that's starting into the XML field. That may have been remedied in the 2nd edition, and to be fair, there weren't a lot of tools available for the Mac user when this was written. I did find some Mac tools and found it humorous how the Windows, Java and Unix tools require extensive use of the command line, altering class paths, etc, while the Mac version was "drag the file onto the icon" to accomplish the exact same thing. But that's how the Mac world works.
