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

DESCRIPTION
       The NodeList interface provides the abstraction of an ordered collec-
       tion of nodes, without defining or constraining how this collection is
       implemented.

       The items in the NodeList are accessible via an integral index, start-
       ing 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.

       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 descen-
           dants so the objects can be claimed for garbage collection. The
           objects should not be used afterwards.
