HTMLCollection (Java SE 9 & JDK 9 )

```
public interface HTMLCollection
```
An HTMLCollection is a list of nodes. An individual node may be accessed by either ordinal index or the node'sname or id attributes. Note: Collections in the HTML DOM are assumed to be live meaning that they are automatically updated when the underlying document is changed.
See also the Document Object Model (DOM) Level 2 Specification.

Since:

1.4, DOM Level 2

- Method Detail
  - getLength
```
int getLength()
```
    This attribute specifies the length or size of the list.
  - item
```
Node item(int index)
```
    This method retrieves a node specified by ordinal index. Nodes are numbered in tree order (depth-first traversal order).
    
    Parameters:
    
    index - The index of the node to be fetched. The index origin is 0.
    
    Returns:
    
    The Node at the corresponding position upon success. A value of null is returned if the index is out of range.
  - namedItem
```
Node namedItem(String name)
```
    This method retrieves a Node using a name. It first searches for a Node with a matching id attribute. If it doesn't find one, it then searches for a Node with a matching name attribute, but only on those elements that are allowed a name attribute.
    
    Parameters:
    
    name - The name of the Node to be fetched.
    
    Returns:
    
    The Node with a name or id attribute whose value corresponds to the specified string. Upon failure (e.g., no node with this name exists), returns null .
