NamedNodeMap
The NamedNodeMap interface represents a collection of Attr objects. Objects inside a NamedNodeMap are not in any particular order, unlike NodeList, although they may be accessed by an index as in an array.
Indexable
[index: number]: Attr
Methods
[iterator]()
iterator: ArrayIterator<Attr>;
Returns
getNamedItem()
getNamedItem(qualifiedName): Attr | null;
The getNamedItem() method of the NamedNodeMap interface returns the Attr corresponding to the given name, or null if there is no corresponding attribute.
Parameters
| Parameter | Type |
|---|---|
qualifiedName | string |
Returns
Attr | null
getNamedItemNS()
getNamedItemNS(namespace, localName): Attr | null;
The getNamedItemNS() method of the NamedNodeMap interface returns the Attr corresponding to the given local name in the given namespace, or null if there is no corresponding attribute.
Parameters
| Parameter | Type |
|---|---|
namespace | string | null |
localName | string |
Returns
Attr | null
item()
item(index): Attr | null;
The item() method of the NamedNodeMap interface returns the item in the map matching the index.
Parameters
| Parameter | Type |
|---|---|
index | number |
Returns
Attr | null
removeNamedItem()
removeNamedItem(qualifiedName): Attr;
The removeNamedItem() method of the NamedNodeMap interface removes the Attr corresponding to the given name from the map.
Parameters
| Parameter | Type |
|---|---|
qualifiedName | string |
Returns
removeNamedItemNS()
removeNamedItemNS(namespace, localName): Attr;
The removeNamedItemNS() method of the NamedNodeMap interface removes the Attr corresponding to the given namespace and local name from the map.
Parameters
| Parameter | Type |
|---|---|
namespace | string | null |
localName | string |
Returns
setNamedItem()
setNamedItem(attr): Attr | null;
The setNamedItem() method of the NamedNodeMap interface puts the Attr identified by its name in the map. If there is already an Attr with the same name in the map, it is replaced.
Parameters
| Parameter | Type |
|---|---|
attr | Attr |
Returns
Attr | null
setNamedItemNS()
setNamedItemNS(attr): Attr | null;
The setNamedItemNS() method of the NamedNodeMap interface puts the Attr identified by its name in the map. If there was already an Attr with the same name in the map, it is replaced.
Parameters

readonly length: number;
The read-only length property of the NamedNodeMap interface is the number of objects stored in the map.
