RSS Browser

Our application has two basic screens. One shows a selection of URLs, each pointing to an RSS file, and allows the user to choose one (or supply a new URL). The other screen opens the URL and examines the channel that it returns.

URL Choice Screen

First we construct a little MovieClip called a ChannelPick (Figure 18.3). It is used to display, edit, and choose a single URL. It presents the variable url to the user as an editable line of text. Of course, url is specific to the namespace of this MovieClip instance, so a screenful of ChannelPick instances will not interfere with one another.
