XML slideshow loop

[mhalak]

Im building a flash portfolio/slideshow using XML to dynamically load external .swfs.
The problem is with gettingthe .swfs( displayed in a center slider ) to display themselves in a loop...

I think it starts with comparing the length of the childnodes with the numbered ID attribute - to see if its come to the last one - and then reset the node atribute to loop, in order to display the beginning to the sequence.
Im not sure of the logic/syntax to resolve.

for example, there might be 5 swfs to display in sequence. The movie clip they are displayed in has spaces for 12 images, so id like the first 5 images to repeat, by loop to fill up the spaces.

Thanks for reading my post!

function startSlideShow(success)
{
if (success == true)
{
rootNode = testXML.firstChild; // this is the 'DDGportfolio' from XML...same as output_XMLroot =this.firstChild.nodeName;
totalCategories = rootNode.childNodes.length;
firstCategory = rootNode.childNodes[0].attributes.name;
currentCategory = firstCategory;
//nextCategory = rootNode.firstChild.nextSibling;
currentcategoryIndex = 1;
updateCategory(firstCategory);
categoryPortfolioitems = rootNode.firstChild.childNodes.length;// counts portfolio items total within category
firstSlideNode = rootNode.childNodes[0]. firstChild;
