IXMLDOMNode.parentNode (C#)

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 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.

using Microsoft.WindowsMediaServices.Interop;
using interop_msxml;

// Declare variables.
WMSServer Server;
IXMLDOMDocument Playlist;
IXMLDOMNode currNode;
IXMLDOMNode newNode;

try {
    // Create a new WMSServer object.
    Server = new WMSServerClass();

    // Create a new playlist object.
    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.
    currNode = Playlist.documentElement.childNodes[1].childNodes[0];

    // Retrieve the parent node.
    newNode = currNode.parentNode;
}
catch (Exception e) {
    // TODO: Handle exceptions.
}
