SyntaxstrValue = objDOMDocument.nodeName
RemarkThis property is read-only. Depending on the type of
Node, this property returns a string containing the Node's name. This is
especially useful with elements and attributes. Table details what is
being represented by the nodeName property for the different interfaces of the
DOMDocument.

nodeNames; therefore, they return the following string literals of what is being
referenced.

ExampleWhen we want to populate the textboxes on a VB form, we
use the nodeName property to work with a Select Case as the decider of which
text box should be populated.
In the following example, we have already obtained a
reference to an element, which in this case is the PERSON element from our main
XML example. We are now looping through its child Nodes, differentiating which
Node is current by its nodeName property.
For Each objChildElement In objPersonElement.childNodes
If objChildElement.nodeType = NODE_ELEMENT Then
Select Case UCase(objChildElement.nodeName)
Case "NAME"
txtName.Text = objChildElement.nodeTypedValue
Case "ADDRESS"
txtAddress.Text = objChildElement.nodeTypedValue
Case "TEL"
txtTel.Text = objChildElement.nodeTypedValue
Case "FAX"
txtFax.Text = objChildElement.nodeTypedValue
Case "EMAIL"
txtEmail.Text = objChildElement.nodeTypedValue
End Select
End If
Next objChildElement
