Duplicate scene without instancing

Hello! I'm duplicating a scene, wich have some actionscript to read XML.

I want to duplicate it, to put the second scene reading another XML file, but after the duplication I correct the code on the second scene and it also change the code on the first scene.

How can I make this without instancing the first scene, being both scenes independent

why dont you make only one function for reading the xml
and call it with a parameter ?
i.e. :
function ReadXML(fileName)
{
// do the xml reading from fileName
}

and when u call it :
ReadXML("file1.xml"); //or whatever xml u want to read

Hi ice.
Yap, it's a good idea, I'll implemente the solution that you sugest, it possible increase the processing speed.

Thanks for the tip!
