Dispaly clickable buttons based on number of similar nodes in an XML file?

programming flash
1

I have a flash gallery (that works ok as it is) however I’d like to upgrade it a bit and I’m stumped.

Right now there is a single image for each portfolio item pulled from an XML file. Some portfolio items however have more than 1 image. Some have 2 and a few have up to 4 or 5.

How can flash automatically see how many similar nodes there are within a set and then display a clickable “1, 2, 3, etc” button below the image to view each photo or if there is only 1 photo, no numbers will appear at all?

Thanks!
Neil

They will use a format similar as shown below. Notice how the first one only has 1 image and the second has 3 image nodes.
