NamedNodeMap.item()
The item() method of the NamedNodeMap interface
returns the item in the map matching the index.
Note: This method is also called when you use the operator [] syntax.
So, myMap[i]is equivalent to myMap.item(i) where i is a Number.

let result = "The attribute map contains: \n"
result += "0: " + attrMap.item(0).name + "\n";
