NodeList
| org.w3c.dom.NodeList |
The NodeList interface provides the abstraction of an ordered
collection of nodes, without defining or constraining how this collection
is implemented. NodeList objects in the DOM are live.
The items in the NodeList are accessible via an integral
index, starting from 0.
See also the Document Object Model (DOM) Level 3 Core Specification.
