IXMLDOMNode.hasChildNodes (C#)

The hasChildNodes method returns a Boolean value indicating whether this node has children.

Syntax

  bValue = IXMLDOMNode
  .hasChildNodes();

Parameters

This method takes no parameters.

Return Values

Returns true if this node has children, and false if it does not.

Remarks

This method always returns false for nodes that, by definition, cannot have children.

Example Code

The following example checks a node to determine whether it has any child nodes. If it does, the number of child nodes is displayed.

using Microsoft.WindowsMediaServices.Interop;
using interop_msxml;

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

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 root element.
    currNode = Playlist.documentElement.firstChild;

    // Check whether the node has child nodes.
    if (currNode.hasChildNodes() == true)
        MessageBox.Show(currNode.childNodes.length.ToString());
    else
        MessageBox.Show("no child nodes");
}
catch (Exception e) {
    // TODO: Handle exceptions.
}
