ListXxorY

Returns a new list, composed of elements that were in either original script, but not both.

Note: This is not the same as getting rid duplicates by preserving just one of each duplicated item. It goes further, and removes both items.

list ListXxorY(list lx, list ly) { // return elements that are in X or Y but not both
    return ListXnotY( lx, ly) + ListXnotY( ly, lx);
}
 

Example:

 
list l1 = ["a","b","c","d"];
list l2 = ["a","1","b","2","c","3"];
 
default{
   state_entry() {
      llSay(0, "Elements that are in x list or y list but not both: " + llList2CSV(ListXxorY(l1,l2)));
      //will say: d, 1, 2, 3
   }
}
