NamedNodeMap: getNamedItem() method
The getNamedItem() method of the NamedNodeMap interface returns the Attr corresponding to the given name, or null if there is no corresponding attribute.
Note: This method is also called when you use the operator [] syntax.
So, myMap[str]is equivalent to myMap.getNamedItem(str) where str is a string.
