IXMLDOMNode.firstChild (C#)
The firstChild property contains the first child of the node.
Syntax
IXMLDOMNode = IXMLDOMNode.firstChild;
Remarks
The property is read-only. It returns the first child node. If there are no children, it returns NULL.
The value of the IXMLDOMNode object returned depends on the type of node on which the firstChild 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 first child node for that element node.
Node type | Value returned |
NODE_ATTRIBUTE NODE_DOCUMENT NODE_ELEMENT |
Returns the first child node. If there are no children, it returns NULL. |
NODE_COMMENT NODE_PROCESSING_INSTRUCTION NODE_TEXT |
Returns NULL. This node type cannot have children. |
Example Code
The following example retrieves the first child node of the top-level node.
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; } catch (Exception e) { // TODO: Handle exceptions. }
