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.
