XML FOR DOMINO


NamedNodeMap
Objects implementing the NamedNodeMap interface are used to represent collections of nodes that can be accessed by name. NamedNodeMap does not inherit from NodeList; NamedNodeMaps 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.

Methods

getLength

getNamedItem

Item

removeNamedItem

setNamedItem

getLength

The number of nodes in the map. The range of valid child node indices is 0 to length-1 inclusive.

Syntax:

public int getLength()

getNamedItem

Retrieves a node specified by name.

Syntax:

public Node getNamedItem(java.lang.String name)

Parameters:


Return value:

item

Returns the nth item in the map. If index (n) is greater than or equal to the number of nodes in the map, this returns null.

Syntax:

public Node item(int index)

Parameters:


Return value:

removeNamedItem

Removes a node specified by name. If the removed node is an Attr with a default value it is immediately replaced.

Syntax:

public Node removeNamedItem(java.lang.String name)
          throws DOMException

Parameters:


Return value:
Throws:

DOMException - NOT_FOUND_ERR: Raised if there is no node named name in the map.

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 given an alias.

Syntax:

public Node setNamedItem(Node arg)
       throws DOMException

Parameters:


Return value:
Throws:
