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
; NamedNodeMap
s 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.
NamedNodeMap ()

NamedNodeMap (const NamedNodeMap &other)
| NamedNodeMap |
NamedNodeMap & operator = (const NamedNodeMap &other)
| operator = |
~NamedNodeMap ()
| ~NamedNodeMap |
unsigned long length ()
| length |
[const]
The number of nodes in the map. The range of valid child node
indices is 0 to length-1
inclusive.
Node getNamedItem ( const DOMString &name )
| getNamedItem |
[const]
Retrieves a node specified by name.
Parameters:
name | Name of a node to retrieve. |
Returns: A Node
(of any type) with the specified
name, or null
if the specified name did not
identify any node in the map.
Node setNamedItem ( const Node &arg )
| setNamedItem |
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.
NO_MODIFICATION_ALLOWED_ERR: 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.
Parameters:
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.
|
Returns: If the new Node
replaces an existing
node with the same name the previously existing Node
is returned, otherwise null
is returned.
Throws: DOMException, WRONG_DOCUMENT_ERR:, Raised, if, , arg,
, was, created, from, a, different, document, than, the, one, that, created, the, , NamedNodeMap,
, .
Node removeNamedItem ( const DOMString &name )
| removeNamedItem |
Removes a node specified by name. If the removed node is an
Attr
with a default value it is immediately
replaced.
Parameters:
name | The name of a node to remove. |
Returns: The node removed from the map or null
if
no node with such a name exists.
Throws: DOMException, NOT_FOUND_ERR:, Raised, if, there, is, no, node, named, , name,
, in, the, map.
Node item ( unsigned long index )
| item |
[const]
Returns the index
th item in the map. If
index
is greater than or equal to the number of nodes
in the map, this returns null
.
Parameters:
index | Index into the map. |
Returns: The node at the index
th position in the
NamedNodeMap
, or null
if that is
not a valid index.
Node getNamedItemNS ( const DOMString &namespaceURI,
const DOMString &localName )
| getNamedItemNS |
[const]
Introduced in DOM Level 2
Retrieves a node specified by local name and namespace URI. HTML-only DOM implementations do not need to implement this method.
Parameters:
namespaceURI | The namespace URI of the node to retrieve. |
localName | The local name of the node to retrieve. |
Returns: A Node (of any type) with the specified local name and namespace URI, or null if they do not identify any node in this map.
Node setNamedItemNS ( const Node &arg )
| setNamedItemNS |
Introduced in DOM Level 2
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. HTML-only DOM implementations do not need to implement this method.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map 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.
Parameters:
arg | A node to store in this map. The node will later be accessible using the value of its namespaceURI and localName attributes. |
Returns: If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.
Throws: DOMException, WRONG_DOCUMENT_ERR:, Raised, if, arg, was, created, from, a, different, document, than, the, one, that, created, this, map.
Node removeNamedItemNS ( const DOMString &namespaceURI,
const DOMString &localName )
| removeNamedItemNS |
Introduced in DOM Level 2
Removes a node specified by local name and namespace URI. A removed attribute may be known to have a default value when this map contains the attributes attached to an element, as returned by the attributes attribute of the Node interface. If so, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable. HTML-only DOM implementations do not need to implement this method.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
Parameters:
namespaceURI | The namespace URI of the node to remove. |
localName | The local name of the node to remove. |
Returns: The node removed from this map if a node with such a local name and namespace URI exists.
Throws: DOMException, NOT_FOUND_ERR:, Raised, if, there, is, no, node, with, the, specified, namespaceURI, and, localName, in, this, map.
