public class NamedNodeMapImpl extends Object implements NamedNodeMap, Serializable
Only one Node may be stored per name; attempting to store another will replace the previous value.
NOTE: The "primary" storage key is taken from the NodeName attribute of the node. The "secondary" storage key is the namespaceURI and localName, when accessed by DOM level 2 nodes. All nodes, even DOM Level 2 nodes are stored in a single Vector sorted by the primary "nodename" key.
NOTE: item()'s integer index does _not_ imply that the named nodes must be stored in an array; that's only an access method. Note too that these indices are "live"; if someone changes the map's contents, the indices associated with nodes may change.

index
- Which item to retrieve. Note that indices are just an
enumeration of the current contents; they aren't guaranteed to be
stable, nor do they imply any promises about the order of the
NamedNodeMap's contents. In other words, DO NOT assume either that
index(i) will always refer to the same entry, or that there is any
stable ordering of entries... and be prepared for double-reporting
or skips as insertion and deletion occur.public Node getNamedItem(String name)
