Now we are going to look at using the external XML data in our slideshow.…Remember that your external XML data is set up as follows. We are going to tab…over to TextEdit to look at the XML file. So gallery is the root XML element,…then there is a repeating element called image. Each one of those has a child…element called file and one called title. So we are going to be able to access those…in this movie.…Let's go over to Flash and I'm going to do that inside of the updateData method. …Remember the updateData method is the last thing that happens before…the changeEvent occurs. So this is what controls how the data is manipulated in…this particular Model. So I'm just basically going to set all of the properties…based on the currentIndex.…
Remember that the currentIndex is already in bounds when the updataData method runs. …That's all based on how everything is set up in the Model class. So first…currentImage = images and the index is going to be currentIndex. On the next line, …set the value of totalItems. We will set that equal to images.length and…
