With this book, I've introduced a wide variety of sample code listings. My intent with this Appendix is to reproduce some of the code listings that introduce key concepts, with additional documentation.
Chapter 1 included sample listings of data in various formats, including XML, for comparison purposes. Listing 1-3 introduced a simple hierarchical XML structure for the high-grossing movie listing. This listing introduced several XML node types including elements, attributes, processing instructions, comments, and text nodes.
Example 1-3. Modified Sample XML
<?xml version = "
1.0" encoding = "
High-grossing movie listing--> <movies> <film> <?
style superhero?> <name>
