As you can see from this example, it is very easy to access web

services from Flex. It’s also easy to parse their contents using

the E4X syntax built directly into ActionScript 3, which makes

querying XML data as easy as using standard dot notation. It’s

nice to wrap the whole thing up with a display using a list of

images managed by TileList with a custom itemRenderer.
