- arg
- A node to store in this map. The node will later be accessible using the value of its namespaceURI and localName attributes.
Documentation for this section has not yet been entered.
Type Reason Org.W3c.Dom.DOMException WRONG_DOCUMENT_ERR: Raised if arg was created from a different document than the one that created this map.
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.
HIERARCHY_REQUEST_ERR: Raised if an attempt is made to add a node doesn't belong in this NamedNodeMap. Examples would include trying to insert something other than an Attr node into an Element's map of attributes, or a non-Entity node into the DocumentType's map of Entities.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature "XML" and the language exposed through the Document does not support XML Namespaces (such as []).
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.
Per []
, applications must use the value null as the namespaceURI parameter
for methods if they wish to have no namespace.
