IXMLDOMNode::put_nodeTypedValue Method

[This is preliminary documentation and subject to change.]

Contains this node's value expressed in its defined data type.

Visual Basic Syntax

objXMLDOMNode.nodeTypedValue = strValue

C/C++ Syntax

HRESULT put_nodeTypedValue(

    VARIANT typedValue);

Parameters

typedValue

[out]
Value of this node in its defined data type, if such a data type is defined.

C/C++ Return Values

S_OK

Value returned if successful.

E_INVALIDARG

Value returned if typedValue is null.

E_FAIL

Value returned if an error occurs.

Remarks

This value depends on the value of the IXMLDOMNode interface's nodeType property.

NODE_ATTRIBUTE Returns the value in the data representation of the type specified in the schema for the attribute. (Data types are specified using the dt:dt attribute, and because attributes cannot be applied to attributes, the attribute's data type can be specified only in the schema.) If no type was specified, returns a string identical to the nodeValue property. If the new value is not of the type specified in the schema or cannot be coerced to the type specified in the schema, an error occurs.
NODE_CDATA_SECTION, NODE_COMMENT, NODE_DOCUMENT, NODE_DOCUMENT_FRAGMENT, NODE_DOCUMENT_TYPE, NODE_ENTITY, NODE_NOTATION, NODE_PROCESSING_INSTRUCTION Returns a string that is equal to the nodeValue property. These node types do not have data types.
NODE_ELEMENT Returns the value in the data representation of the type specified on the element instance (using the dt:dt attribute) or specified in the schema. If no type was specified on the instance or in the schema, returns a string identical to the nodeValue property. If the element has an attribute data type, returns null.
NODE_ENTITY_REFERENCE Returns the value in the data representation of the type specified for the referenced entity. This is limited to entities with a single data type on the root level element of the subtree corresponding to the entity. If no data type was specified, returns a string identical to the nodeValue property.
NODE_TEXT Returns the value in the data representation of the type of the containing element. If the containing element was not typed, returns a string identical to the nodeValue property.

The data type for this node is defined in its dataType property. This property also depends on the value of the node type, in the nodeType property.

Although you can explicitly set the nodeTypedValue property with a particular data type in the VARIANT, the set operation does not change the data type. The value in the VARIANT is coerced to the data type specified in the dataType property, and the set operation returns an error if the type coercion is not possible.

Changes to this property are also immediately available from the nodeValue property.
