If my xml has two nodes with the same name, how to know the node I'm into?

I have the following xml file that contains twice the element manufacturedMaterial.

I'm using NodeList nodes = dom.getElementsByTagName("manufacturedMaterial"); to access the elements of manufacturedMaterial and add some subelements. However, the subelements are added also to the second manufacturedMaterial.

The code I'm using is:

for (int i = 0; i < nodes.getLength(); i++) {
            Node node = nodes.item(i);
}

Is there a way to check if I'm in the first or second node of manufacturedMaterial?
