XNode.NextNode Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the next sibling node of this node.

Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)

Syntax

'Declaration
Public ReadOnly Property NextNode As XNode

public XNode NextNode { get; }

Property Value

Type: System.Xml.Linq.XNode
The XNode that contains the next sibling node.

Remarks

If this XNode does not have a parent, or if there is no next node, this property returns nulla null reference (Nothing in Visual Basic).

Examples

The following example uses this property to loop through nodes.

Dim output As New StringBuilder
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
    output.Append(sb.ToString())
    output.Append(Environment.NewLine)

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

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
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: " + 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;
    }
    output.Append(sb.ToString() + Environment.NewLine);
}
while ((node = node.NextNode) != null);

OutputTextBlock.Text = output.ToString();
