![]() ![]() In summary: If the attribute has an assigned value in the document then Make a new attribute available with specified set toįalse and the default value (if one exists). To re-specify the attribute as the default valueįrom the DTD, the user must delete the attribute. The default value) then the specified flag is automaticallyįlipped to true. If the userĬhanges the value of the attribute (even if it ends up having the same value as Implementation is in charge of this attribute, not the user. If this attribute was explicitly given a value in the original document, GetParentNode, getPrefix, getPreviousSibling, NodeĬloneNode, getAttributes, getChildNodes, getFirstChild, getLastChild, getLocalName, getNamespaceURI, getNextSibling, getNodeName, getNodeType, getNodeValue, getOwnerDocument, Value of the attribute is returned as a string. Was explicitly given a value in the original document, this is NOTATION_NODE, PROCESSING_INSTRUCTION_NODE,Įlement node this attribute is attached to or null if NodeĮLEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, Because the DOM Core is notĪware of attribute types, it treats all attribute values as simple strings,Įven if the DTD or schema declares them as having tokenized types.įields inherited from interface. In XML, where the value of an attribute can contain entity references, theĬhild nodes of the Attr node may be either Text orĮntityReference nodes (when these are in use see the description The nodeValue attribute on the Attr instance can alsoīe used to retrieve the string version of the attribute's value(s). Value otherwise, if there is a declaration for this attribute, and thatĭeclaration includes a default value, then that default value is theĪttribute's effective value otherwise, the attribute does not exist on thisĮlement in the structure model until it has been explicitly added. Has been explicitly assigned any value, that value is the attribute's effective The attribute's effective value is determined as follows: if this attribute Inheriting the Node interface, but they also are quite Short, users and implementors of the DOM need to be aware thatĪttr nodes have some things in common with other objects ![]() However, they can be associated withĮlement nodes contained within a DocumentFragment. Furthermore,Īttr nodes may not be immediate children of aĭocumentFragment. With this should make it more efficient to implement such features as defaultĪttributes associated with all elements of a given type. Rather than having a separate identity from the elements they are associated ![]() The DOM takes the view that attributes are properties of elements Thus, the NodeĪttributes parentNode, previousSibling, and Not consider them part of the document tree. They are not actually child nodes of the element they describe, the DOM does Typically the allowable values for the attributeĪre defined in a document type definition.Īttr objects inherit the Node interface, but since The Attr interface represents an attribute in anĮlement object.
