NAME

       XML::DOM::NodeList - A node list as used by XML::DOM

DESCRIPTION

       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 always reflect changes to the DOM
       tree, the NodeList returned by getElementsByTagName is not live in this implementation. See CAVEATS for
       details.

   METHODS
       item (index)
           Returns the indexth item in the collection. If index is greater than or equal to the number of nodes
           in the list, this returns undef.

       getLength
           The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.

   Additional methods not in the DOM Spec
       dispose
           Removes all circular references in this NodeList and its descendants so the objects can be claimed
           for garbage collection. The objects should not be used afterwards.
