XML::DOM::NodeList - A node list as used by XML::DOM
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.
Although the DOM spec states that all NodeLists are "live" in that they allways reflect changes to the DOM tree, the NodeList returned by getElementsByTagName is not live in this implementation. See CAVEATS for details.
