Join Todd Perkins for an in-depth discussion in this video Visualizing XML, part of ActionScript 3.0: Working with XML.
XML data is stored in a hierarchy. It's called an XML tree. Let's talk about what XML trees are and kind of what they look like. Here's an example of an XML tree. I want you to imagine that you're creating a slideshow and you have a whole bunch of images in that slideshow and you want to have a database or an area that stores all the information about each image in the slideshow. So each image could have an associated title, a description, an artist and a filename linked to it. In XML you connect all of that data to an element. So in this example of an XML tree, the image element shown on the left side of your screen is connected to a title, a description, an artist and a file name. So in one XML file you may have many different image elements, but each one of those has associated data and so there's a look at an XML tree.
Now that you have an idea of how XML data works and what an XML tree is, let's take a look at an actual XML file.
