IXMLDOMNode.parentNode (Visual Basic .NET)

The parentNode property contains the parent node of the IXMLDOMNode object.

Syntax

  IXMLDOMNode = IXMLDOMNode.parentNode

Remarks

The property is read-only. All nodes except Document and Attribute nodes can have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, the parent is NULL.

The value of the IXMLDOMNode object that is returned depends on the type of node on which the parentNode property is called, as shown in the following table. For example, if the node type is NODE_ELEMENT, an IXMLDOMNode object is returned containing the parent node for that element node.

Node type	Value returned
NODE_ATTRIBUTE NODE_DOCUMENT	Returns NULL; these nodes do not have parents.
NODE_COMMENT	Returns the element, entity reference, document type, or document containing the comment.
NODE_ELEMENT	Returns the parent node of the element. If the element is the root node in the tree, the parent is the document node. If the node is the document node, parentNode is NULL.
NODE_PROCESSING_INSTRUCTION	Returns the document or element, containing the processing instruction.
NODE_TEXT	Returns the parent element or attribute.

Example Code

The following example creates an IXMLDOMNode object from another node object's parent.

Imports interop_msxml
Imports Microsoft.WindowsMediaServices.Interop

On Error GoTo Err

' Declare variables.
Dim Server As New WMSServerClass()
Dim Playlist As IXMLDOMDocument
Dim currNode As IXMLDOMNode
Dim newNode As IXMLDOMNode

' Create a new playlist object.
Set Playlist = Server.CreatePlaylist

' Load a playlist.
Playlist.Load ("file://c:\wmpub\wmroot\simple.wsx")

' Retrieve the first child node of the second child node
' in the root element.
Set currNode = Playlist.documentElement.childNodes.Item(1).childNodes.Item(0)

' Retrieve the parent node.
Set newNode = currNode.parentNode
Exit Sub

Err:
' TODO: Handle errors.
