Method Detail

getNamedItem

public Node getNamedItem(java.lang.String name)

DOM: Implements NamedNodeMap.getNamedItem(String).

Specified by:

getNamedItem in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

nameThe - nodeName of a node to retrieve.

Returns:

A Node (of any type) with the specified nodeName, or null if it does not identify any node in this map.

setNamedItem

public Node setNamedItem(Node arg)
                  throws DOMException

DOM: Implements NamedNodeMap.setNamedItem(Node).

Specified by:

setNamedItem in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

argA - node to store in this map. The node will later be accessible using the value of its nodeName attribute.

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.
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.

removeNamedItem

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

DOM: Implements NamedNodeMap.removeNamedItem(String).

Specified by:

removeNamedItem in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

nameThe - nodeName of the node to remove.

Returns:

The node removed from this map if a node with such a name exists.

Throws:

DOMException - NOT_FOUND_ERR: Raised if there is no node named name in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

item

public Node item(int index)

DOM: Implements NamedNodeMap.item(int).

Specified by:

item in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

indexIndex - into this map.

Returns:

The node at the indexth position in the map, or null if that is not a valid index.

getLength

public int getLength()

DOM: Implements NamedNodeMap.getLength().

Specified by:

getLength in interface NamedNodeMap

getNamedItemNS

public Node getNamedItemNS(java.lang.String namespaceURI,
                           java.lang.String localName)

DOM: Implements NamedNodeMap.getNamedItemNS(String,String).

Specified by:

getNamedItemNS in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

namespaceURIThe - namespace URI of the node to retrieve.

localNameThe - 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.

setNamedItemNS

public Node setNamedItemNS(Node arg)
                    throws DOMException

DOM: Implements NamedNodeMap.setNamedItemNS(Node).

Specified by:

setNamedItemNS in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

argA - 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.
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.

removeNamedItemNS

public Node removeNamedItemNS(java.lang.String namespaceURI,
                              java.lang.String localName)
                       throws DOMException

DOM: Implements NamedNodeMap.removeNamedItemNS(String,String).

Specified by:

removeNamedItemNS in interface NamedNodeMap

Following copied from interface: org.w3c.dom.NamedNodeMap

Parameters:

namespaceURIThe - namespace URI of the node to remove.

localNameThe - 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.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

setNamedItem

public Node setNamedItem(java.lang.String ns,
                         java.lang.String name,
