The Other Objects
The main interfaces were covered in the previous section. The more specialized interfaces, such as the Element object just extend the more general Node object and add some more specific properties and methods that allow you to access and manipulate the object in a more convenient and specific way.
The Element object offers the facilities (properties and methods) to access and manipulate tag names, attribute names, and attribute values.
