XML DOM - The Attr Object

❮ Previous Next ❯

The Attr object

The Attr object represents an attribute of an Element object. The allowable values for attributes are usually defined in a DTD.

Because the Attr object is also a Node, it inherits the Node object's properties and methods. However, an attribute does not have a parent node and is not considered to be a child node of an element, and will return null for many of the Node properties.

Attr Object Properties

Property Description
baseURI Returns the absolute base URI of the attribute
isId Returns true if the attribute is known to be of type ID, otherwise it returns false
localName Returns the local part of the name of the attribute
name Returns the name of the attribute
namespaceURI Returns the namespace URI of the attribute
nodeName Returns the name of the node, depending on its type
nodeType Returns the type of the node
nodeValue Sets or returns the value of the node, depending on its type
ownerDocument Returns the root element (document object) for an attribute
ownerElement Returns the element node the attribute is attached to
prefix Sets or returns the namespace prefix of the attribute
schemaTypeInfo Returns the type information associated with this attribute
specified Returns true if the attribute value is set in the document, and false if it's a default value in a DTD/Schema.
textContent Sets or returns the textual content of an attribute
value Sets or returns the value of the attribute
