NodeList (Org.W3C.DOM Package)
The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented.
The items in the NodeList are accessible via an integral index, starting from 0. .
See the following for methods.
getLength
The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.
Syntax:
public int getLength()
item
Returns the nth item in the collection. If index (n) is greater than or equal to the number of nodes in the list, this returns null.
Syntax:
public Node item(int index)
Parameters:
index - Index into the collection.
Return value:
The node at the nth position in the NodeList, or null if that is not a valid index.
