Displaying photos from an XML file

Here's my next little challenge: have to build an app that shows a bunch of photos (listed in an XML file) based upon certain criteria in the XML data. First view will show ALL the photos, and then the user will whittle down the choices/photos based upon criteria they select via check boxes.

I'm sure I can now figure out how to pull the XML data into the application. I'll have to build a listener for the check box component(s), which shouldn't be difficult. The onClick event would then have to search through the XML/array and show only the user-selected data. It would be good also if the pictures were actually pulled from the server's hard drive rather than having them stored in the Flash file. That would allow the site's owner to easily add images by simply copying them to the server and adding data to the XML. Is that do-able, and if so, can anyone put me on the right path (theorhetically) to developing it?

The other question I have at this pre-planning stage is this: ALL the pix are certainly not going to fit on the stage at one time. I am going to have to have a finite number of pix, say six, visible on the stage, and then allow the user to filter through the as-yet-unseen images by clicking on a number (Page 2 of 7), or something along those lines.

Before I get too deep into the project, can anyone give me some theory on how something like that might be accomplished? I'm trying to kinda map this one out in my head prior to getting knee deep in code.

Thanks!
