General Remarks

Creating an attribute with this method is the same as using createNode Method where the type parameter value is NODE_ATTRIBUTE and no namespace is specified.

You cannot create a namespace-qualified attribute using the createAttribute method. Regardless of whether a namespace prefix is included in name, the namespaceURI Property (IXMLDOMNode) property for the new attribute is set to an empty string, "". An attribute constructed as part of an XML document load operation will never have both a prefix and an empty namespace Uniform Resource Identifier (URI). You can only create a namespace-qualified attribute using the createNode Method of the DOMDocument.

No data value is set for the attribute during the create operation. You can set the value by calling the setAttribute method of the element object.

Although this method creates the new object in the context of this document, it does not automatically add the new object to the document tree. In other words, although the ownerDocument property of the new node points to this document object, the parentNode property is set to Null. To associate the attribute with an element, call the setAttribute method of the IXMLDOMElement object.

The nodeType property has the value NODE_ATTRIBUTE.

This method applies to the following objects and interfaces:

DOMDocument, IXMLDOMAttribute, and IXMLDOMElement.
