  .setAttributeNode(
  IXMLDOMAttribute DOMAttribute
);

Parameters

Example Code

The following example creates an attribute node and adds it to the specified element node.

using Microsoft.WindowsMediaServices.Interop;
using interop_msxml;

// Declare variables.
WMSServer Server;
IXMLDOMDocument Playlist;
IXMLDOMNodeList ElemList;
IXMLDOMElement Elem;
IXMLDOMNode Node;
IXMLDOMAttribute NodeAtt;

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 a list of nodes that matches the query.
    ElemList = Playlist.getElementsByTagName("media");

    // Retrieve the first node in the list.
    Node = ElemList[0];

    // Box the first node into an IXMLDOMElement object.
    Elem = (IXMLDOMElement)Node;

    // Create a new attribute and assign it a value.
    NodeAtt = Playlist.createAttribute("dur");
    NodeAtt.value = ("15s");

    // Add the attribute object named "dur" to the element.
    Elem.setAttributeNode(NodeAtt);
