Remove unused Swatch Groups

[eusoujp]

Hi, guys!

Is there any script code to remove unused core sample group? I know the code to erase color swatches, but not groups.
Exmple to remove color swatches (not groups):

var allDocs = app.documents;

for (var i = 0; i < allDocs.length; i++) {
trashUnusedSwatch (allDocs[i]);
}

function trashUnusedSwatch(myDocument){
var id, sw;
while (myDocument.unusedSwatches[0].name != "") {
id = myDocument.unusedSwatches[0].id;
sw = myDocument.swatches.itemByID(id);
sw.remove();
}
}

Try this:

var allDocs = app.documents;

for (var i = 0; i < allDocs.length; i++) {
    trashUnusedSwatchGroups (allDocs[i]);
}

function trashUnusedSwatchGroups(myDocument){
    for (var j=myDocument.colorGroups.count()-1; j>=0; j--) {
        if(myDocument.colorGroups[j].colorGroupSwatches.length == 0) {
            myDocument.colorGroups[j].remove();
        }
    }
}
