• XML Notes index

Various resources in no particular order (I'll eventually organize them)

I grabbed these books years ago when I heard that the latest HTML standard was xHTML and that soon XML would be the standard. Well, it hasn't happened yet and xHTML is still quite commonplace. Native XML being fed directly to the browser isn't commonplace, yet.

The most useful one of the bunch has to be #1. Though with this book being eight years old, unless you can find it cheap, I would recommend searching for a more recent book

1. XML for the World Wide Web (Visual QuickStart Guide)
   • Errata, examples, etc.
2. Learning XML ¹⁾
   • Errata, etc.
3. XML In A Nutshell
   • Errata, etc.
