nodeTypedValue

Is a member of:

DOMDocument

Syntax

vntValue = objXMLDOMElement.nodeTypedValue

Remark

In VB's object browser, its description of this propery is: property get the strongly typed value of the node. For an element Node, it returns a variant datatype of the contents of the Node. If you're working with an attribute Node, you will only get the value of attribute, which does not return much value. (See nodeValue for working with attribute Nodes.)

If you have used a Schema in your XML, which does not have a datatype specified for the element in the Schema, a string value datatype is the default datatype returned. Otherwise, it returns the data in the specified datatype value. This is the main strength of this property.

When working with an element Node, you could also use the Text property to get the value of a Node. It's a matter of preference.

Example

You cannot use the nodeTypedValue property to set the value of a Node, as it will return a runtime error. You need to use the text property to do this.

In the following example, after loading our DOMDocument, we want to get the value of the first child's value of the first element (firstChild) of the root element (documentElement), using the nodeTypedValue property:

Dim objDOMDocument As DOMDocument

Dim objXMLDOMElement As IXMLDOMElement

Dim strFirstValue As String

Set objDOMDocument = New DOMDocument

objDOMDocument.async = False

objDOMDocument.Load "http://localhost/xmlcode/people2.dtd"

Set objXMLDOMElement = objDOMDocument.documentElement.first-Child

strFirstValue = objXMLDOMElement.firstChild.nodeTypedValue

¬ Get the root Node's first child element.

¬ From the first child of the root Node, get the first child of that element.

¬ This returns "Mark Wilson" from our main XML example.
