Photoshop CS6 Export Nested Layers to PNG? - photoshop

Question

I have a PSD that contains 100s of layers. Most are grouped with individual elements within the groups (nested).
How do I Export to PNG certain individual groups (with nested layers inside of them)?
I don't want to run the Export All Layers to PNG Script, just need to export individual nested groups (layers) to PNG. I've found a few other 3rd party scripts, but they export everything. Only need to export the ones I've selected.
Thanks in advance

This script should do what you want. It works only when you have the group that you want selected (not a layer within that group) I've not extensively tested it and I'm assuming you don't have groups within groups (which becomes a headache)
// export png from group
srcDoc = app.activeDocument;
var allLayers = new Array();
var selectedLayer = srcDoc.activeLayer;
var theLayers = collectAllLayers(app.activeDocument, 0);
var groupName = "";
// function collect all layers
function collectAllLayers (theParent, level)
{
for (var m = theParent.layers.length - 1; m >= 0; m--)
{
var theLayer = theParent.layers[m];
// apply the function to layersets;
if (theLayer.typename == "LayerSet")
{
var goCode = false;
allLayers.push(level + theLayer.name);
groupName = theLayer.name
// alert(level + " " + theLayer.name)
collectAllLayers(theLayer, level + 1)
var subDoc = srcDoc.layers[m];
//alert(subDoc)
var numOfSubLayers = subDoc.layers.length;
//alert(numOfSubLayers)
for (var j = numOfSubLayers -1; j >= 0 ; j--)
{
if (subDoc.layers[j].typename == "ArtLayer")
{
// if the selected (active) layer is in the group
if (theLayer == selectedLayer)
{
var mylayerName = subDoc.layers[j].name
srcDoc.activeLayer = subDoc.layers[j];
// alert("Selected: " + mylayerName + " in " + groupName)
processLayer(mylayerName)
//selectAllLayersInGroup(groupName)
}
}
}
}
}
}
function processLayer(alayername)
{
// duplicate image into new document
