This book is about Oracle XML programming. It covers many Oracle XML related topics like Oracle XDK, XML DB, JDeveloper, Oracle Text/Oracle Secure Enterprise Search (SES), and Oracle Application Express (APEX). For each topic, detailed examples are given and provided as download. I use the examples as a starting point to learn XML programming, Oracle XML DB and building Oracle XML DB applications.
The book is written a very readable style with plenty of code examples. I particularly like the tips and tricks in this book. This is the most up-to-date and practical Oracle XML programming book.
