Flash and XML[c] A Developer[ap]s Guide

Chapter 9. Recursive Approach

This chapter highlights improved programming concepts. It focuses on event-driven code and recursion in the abstract, then as used in ActionScript and as applied to the example code we have been developing. We also try a few approaches to text filtering for whitespace removal, and we face some problems of extracting data from XML.

In doing so we build a graphic browser for XML ” one that functions as an interactive probe into the data structure. The browser extends earlier work we did on a text-based XML tracer. We create event-driven callback routines and recursive tree-walkers.
