Gets the depth of the current node in the XML document.
public:
virtual property int Depth { int get(); };
public override int Depth { get; }
member this.Depth : int
Public Overrides ReadOnly Property Depth As Integer
The depth of the current node in the XML document.
The following example displays each node including its depth, line number, and line position.
