Flash and XML: A Developer's Guide

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...

Looking back at our general XML display code, we see that the problems with our current design are glaring. It is procedural in all the...

The flaw here is obvious. The code works all right, but it is severely limited. It is hideously ugly code—far too redundant, too specific. There...

is a programming technique where one function calls itself to iteratively process a problem (Figure 9.1). Figure 9.1. Flowchart of the Recursive Process RECURSION If you don't get...

First we streamline the shownode function. (This function is independent of the recursion but part of tightening up the code.) The function is renamed trace()....

Our software can read an XML file, clean it up, and examine it in terrific detail. But Flash was not created to print messages to...

We can quickly add interactivity to this picture by putting a button on the attribute counter (Figure 9.4). By pressing this button, the user moves...

At this point we have a very generic XML node viewer. It is useful for browsing XML in a Flash environment. Furthermore, it was useful...
