Parameters
node

Type: System.Web.SiteMapNodeCollection
Returns a read-only SPNavigationNodeCollection that contains the child nodes of the specified SiteMapNode object; otherwise returns a null reference, or an empty collection if no child nodes exist.

The child nodes in the collection represent the subwebs of the Web site represented by the node parameter.
