HTMLCollection is an interface representing a generic collection of elements (in document order) and offers methods and properties for traversing the list.

Note: This interface is called HTMLCollection for historical reasons (before DOM4, collections implementing this interface could only have HTML elements as their items).

HTMLCollections in the HTML DOM are live; they are automatically updated when the underlying document is changed.

public interface HTMLCollection extends Indexable {

The number of items in the collection. Read only.
  int getLength();

Returns the specific node at the given zero-based index into the list. Returns null if the index is out of range.
  Node item(int index);

Returns the specific node whose ID or, as a fallback, name matches the string specified by name. Matching by name is only done as a last resort, only in HTML, and only if the referenced element supports the name attribute. Returns null if no node exists by the given name.
  Node namedItem(String name);
