What sets apart getNamedItem() from getAttribute()?

Do both provide attributes of an XML element? Is there any distinction between the two?

Answer №1

Make sure to save the W3C Document Object Model Core in your bookmarks - it's an invaluable resource.

The Element interface implements the getAttribute method, as defined by the W3C specification,

getAttribute is used to retrieve an attribute value based on its name.

On the other hand, the NamedNodeMap interface includes the getNamedItem method. According to the W3C,

getNamedItem retrieves a node specified by its name.

It is clear that getAttribute returns a string while getNamedItem returns a node, like an object that follows the Attr interface:

interface Attr : Node {
  readonly attribute DOMString        name;
  readonly attribute boolean          specified;
  // Modified in DOM Level 1:
           attribute DOMString        value;
                                        // raises(DOMException) when setting
};

I personally view getAttribute as a very convenient method.
