DOM - NamedNodeMap Object
The NamedNodeMap object is used to represent collections of nodes that can be accessed by name.
Attributes
The following table lists the Property of the NamedNodeMap Object.
| Attribute | Type | Description |
|---|---|---|
| length | unsigned long | It gives the number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive. |
Methods
The following table lists the methods of the NamedNodeMap object.
| S.No. | Methods & Description |
|---|---|
| 1 | getNamedItem () Retrieves the node specified by name. |
| 2 | getNamedItemNS () Retrieves a node specified by local name and namespace URI. |
| 3 | item () Returns the indexth item in the map. If index is greater than or equal to the number of nodes in this map, this returns null. |
| 4 | removeNamedItem () Removes a node specified by name. |
| 5 | removeNamedItemNS () Removes a node specified by local name and namespace URI. |
| 6 | setNamedItem () Adds a node using its nodeName attribute. If a node with that name is already present in this map, it is replaced by the new one. |
| 7 | setNamedItemNS () Adds a node using its namespaceURI and localName. If a node with that namespace URI and that local name is already present in this map, it is replaced by the new one. Replacing a node by itself has no effect. |
