XNode.NextNode Eigenschaft

Definition

Ruft den nächsten nebengeordneten Knoten dieses Knotens ab.Gets the next sibling node of this node.

public:
 property System::Xml::Linq::XNode ^ NextNode { System::Xml::Linq::XNode ^ get(); };
public System.Xml.Linq.XNode NextNode { get; }
public System.Xml.Linq.XNode? NextNode { get; }
member this.NextNode : System.Xml.Linq.XNode
Public ReadOnly Property NextNode As XNode

Eigenschaftswert

XNode

Der XNode, der den nächsten nebengeordneten Knoten enthält.The XNode that contains the next sibling node.

Beispiele

Im folgenden Beispiel wird diese Eigenschaft verwendet, um Knoten zu durchlaufen.The following example uses this property to loop through nodes.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XText("Some Text"),  
    new XElement("Child2",  
        2,  
        new XElement("GrandChild", "GrandChild Content")  
    ),  
    new XComment("a comment"),  
    new XElement("Child3")  
);  
XNode node = xmlTree.Element("Child2");  
do {  
    StringBuilder sb = new StringBuilder();  
    sb.Append(String.Format("NodeType: {0}", node.NodeType.ToString().PadRight(10)));  
    switch (node.NodeType)  
    {  
        case XmlNodeType.Text:  
            sb.Append((node as XText).Value);  
            break;  
        case XmlNodeType.Element:  
            sb.Append((node as XElement).Name);  
            break;  
        case XmlNodeType.Comment:  
            sb.Append((node as XComment).Value);  
            break;  
    }  
    Console.WriteLine(sb.ToString());  
}  
while ((node = node.NextNode) != null);  
Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>Some Text  
            <Child2>2  
                <GrandChild>GrandChild Content</GrandChild>  
            </Child2>  
            <!--a comment-->  
            <Child3>3</Child3>  
        </Root>  

Dim node As XNode = xmlTree.Element("Child2")  
Do  
    Dim sb As StringBuilder = New StringBuilder()  
    sb.Append(String.Format("NodeType: {0}", node.NodeType.ToString().PadRight(10)))  
    Select Case node.NodeType  
        Case XmlNodeType.Text  
            sb.Append(DirectCast(node, XText).Value)  
        Case XmlNodeType.Element  
            sb.Append(DirectCast(node, XElement).Name)  
        Case XmlNodeType.Comment  
            sb.Append(DirectCast(node, XComment).Value)  
    End Select  
    Console.WriteLine(sb.ToString())  

    node = node.NextNode  
Loop While (Not (node Is Nothing))  

Dieses Beispiel erzeugt die folgende Ausgabe:This example produces the following output:

NodeType: Element   Child2  
NodeType: Comment   a comment  
NodeType: Element   Child3  

Hinweise

Wenn kein XNode übergeordnetes Element vorhanden ist, oder wenn kein nächster Knoten vorhanden ist, gibt diese Eigenschaft zurück null .If this XNode does not have a parent, or if there is no next node, this property returns null.
