Hi i have a small problem. I use some script of grid gallery. it works great and its based on xml file with this structure:

<?xml version="1.0" encoding="utf-8"?>
<GALLERY XPOSITION="5" YPOSITION="5" WIDTH="100" HEIGHT="100">
<IMAGE FULL="full_images/image1.jpg" THUMB="thumbs/thumb1.jpg" />
<IMAGE FULL="full_images/image2.jpg" THUMB="thumbs/thumb2.jpg" />
<IMAGE FULL="full_images/image3.jpg" THUMB="thumbs/thumb3.jpg" />
<IMAGE FULL="full_images/image4.jpg" THUMB="thumbs/thumb4.jpg" />
<IMAGE FULL="full_images/image5.jpg" THUMB="thumbs/thumb5.jpg" />
<IMAGE FULL="full_images/image6.jpg" THUMB="thumbs/thumb6.jpg" />
<IMAGE FULL="full_images/image7.jpg" THUMB="thumbs/thumb7.jpg" />
<IMAGE FULL="full_images/image8.jpg" THUMB="thumbs/thumb8.jpg" />
<IMAGE FULL="full_images/image9.jpg" THUMB="thumbs/thumb9.jpg" />
<IMAGE FULL="full_images/image10.jpg" THUMB="thumbs/thumb10.jpg" />
<IMAGE FULL="full_images/image11.jpg" THUMB="thumbs/thumb11.jpg" />
<IMAGE FULL="full_images/image12.jpg" THUMB="thumbs/thumb12.jpg" />
<IMAGE FULL="full_images/image13.jpg" THUMB="thumbs/thumb13.jpg" />
<IMAGE FULL="full_images/image14.jpg" THUMB="thumbs/thumb14.jpg" />
</GALLERY>

In my site I want to show last added 3 thumbs. So in my site will be shown only the one thumbs which number in name of file is highest. Hm I was thinking about ‘for’ construction but i really dont know how to start;/ any ideas?I ve read that I should use sth like that:


var start:int = YourXML..IMAGE.length() - 3;
for(var i:int = start; i < YourXML..IMAGE.length(); i++)
{
    //load your image here using something like:
    // YourXML..IMAGE*.@THUMB
}

but to be honest i really dont know how to start;/
