       XML::DOM::NamedNodeMap - A hash table interface for XML::DOM


       Objects implementing the NamedNodeMap interface are used to represent collections of nodes
       that can be accessed by name. Note that NamedNodeMap does not inherit from NodeList;
       NamedNodeMaps are not maintained in any particular order. Objects contained in an object
       implementing NamedNodeMap may also be accessed by an ordinal index, but this is simply to
       allow convenient enumeration of the contents of a NamedNodeMap, and does not imply that
       the DOM specifies an order to these Nodes.

       Note that in this implementation, the objects added to a NamedNodeMap are kept in order.

       getNamedItem (name)
           Retrieves a node specified by name.

           Return Value: A Node (of any type) with the specified name, or undef if the specified
           name did not identify any node in the map.

       setNamedItem (arg)
           Adds a node using its nodeName attribute.

           As the nodeName attribute is used to derive the name which the node must be stored
           under, multiple nodes of certain types (those that have a "special" string value)
           cannot be stored as the names would clash. This is seen as preferable to allowing
           nodes to be aliased.

            arg  A node to store in a named node map.

           The node will later be accessible using the value of the nodeName attribute of the
           node. If a node with that name is already present in the map, it is replaced by the
           new one.

           Return Value: If the new Node replaces an existing node with the same name the
           previously existing Node is returned, otherwise undef is returned.


           ·   WRONG_DOCUMENT_ERR

               Raised if arg was created from a different document than the one that created the


               Raised if this NamedNodeMap is readonly.

           ·   INUSE_ATTRIBUTE_ERR

               Raised if arg is an Attr that is already an attribute of another Element object.
               The DOM user must explicitly clone Attr nodes to re-use them in other elements.

       removeNamedItem (name)
           Removes a node specified by name. If the removed node is an Attr with a default value
           it is immediately replaced.

           Return Value: The node removed from the map or undef if no node with such a name


           ·   NOT_FOUND_ERR

               Raised if there is no node named name in the map.

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

           Return Value: The node at the indexth position in the NamedNodeMap, or undef if that
           is not a valid index.

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

   Additional methods not in the DOM Spec
           Returns a NodeList with the nodes contained in the NamedNodeMap.  The NodeList is
           "live", in that it reflects changes made to the NamedNodeMap.

           When this method is called in a list context, it returns a regular perl list
           containing the values. Note that this list is not "live". E.g.

            @list = $map->getValues;        # returns a perl list
            $nodelist = $map->getValues;    # returns a NodeList (object ref.)
            for my $val ($map->getValues)   # iterate over the values

       getChildIndex (node)
           Returns the index of the node in the NodeList as returned by getValues, or -1 if the
           node is not in the NamedNodeMap.

           Removes all circular references in this NamedNodeMap and its descendants so the
           objects can be claimed for garbage collection. The objects should not be used
