XML in a Nutshell, 3rd Edition

Name

prefix: DOMString(2)

Synopsis

Represents the namespace prefix of this node, used for nodes that support namespace prefixes. For ELEMENT_NODE and ATTRIBUTE_NODE type nodes, changing the namespace prefix also affects the nodeName, tagName, and name attributes. Since these properties hold the qualified name of the node, changing the prefix also updates it.

Exceptions

INVALID_CHARACTER_ERR

Raised if the prefix includes an illegal character.

NO_MODIFICATION_ALLOWED_ERR

Indicates that the prefix attribute is read-only for this DOM object type.

NAMESPACE_ERR

Raised if the prefix is malformed, according to the rules of namespace identifier formation. This exception is also raised if the namespaceURI attribute is null, or if an attempt was made to violate the XML rules of identifier formation. Such an attempt includes invalid use of the xml or xmlns identifier. For more information about namespaces, see Chapter 4.
