IXMLDOMNode.previousSibling (C#)

The previousSibling property contains the previous sibling of this node in the parent's child list.

Syntax

  IXMLDOMNode = IXMLDOMNode.previousSibling;

Remarks

The property is read-only.

The value of the IXMLDOMNode object returned depends on the type of node on which the previousSibling 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 node that immediately precedes that element node.

Node type Value returned
NODE_ATTRIBUTE
NODE_DOCUMENT		 Always returns NULL; these node types do not appear as children of any other nodes.
NODE_ELEMENT
NODE_PROCESSING_INSTRUCTION
NODE_TEXT		 Returns the node immediately preceding this node in its parent's child list. Returns NULL if no such node exists.

Example Code

The following example creates an IXMLDOMNode object and sets it to the previous sibling of the current node.

using Microsoft.WindowsMediaServices.Interop;
using interop_msxml;

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

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 second child node of the root element.
    currNode = Playlist.documentElement.childNodes[1];

    // Retrieve the previous sibling.
    prevNode = currNode.previousSibling;
}
catch (Exception e) {
    // TODO: Handle exceptions.
}
