XNode.IsAfter Method (XNode)

 

Determines if the current node appears after a specified node in terms of document order.

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

Public Function IsAfter (
	node As XNode
) As Boolean

Parameters

node
Type: System.Xml.Linq.XNode

The XNode to compare for document order.

Return Value

Type: System.Boolean

true if this node appears after the specified node; otherwise false.

The XContainer stores its child nodes as a singly-linked list of XNode objects. This means that the CompareDocumentOrder method must traverse the ancestors of the two nodes being compared until it finds the common parent. Then it must traverse the list of the common parent’s child nodes to determine the order of the two nodes being compared. Therefore, using this method might affect your performance.

The following example uses this method.


                Dim xmlTree As XElement = _ 
        <Root>Text content.
            <Child1>child1 content</Child1>
            <Child2>child2 content</Child2>
            <Child3>child3 content</Child3>More text content.
            <Child4>child4 content</Child4>
            <Child5>child5 content</Child5>
        </Root>

Dim child3 As XElement = xmlTree.<Child3>(0)
Dim child5 As XElement = xmlTree.<Child5>(0)
If (child5.IsAfter(child3)) Then
    Console.WriteLine("Child5 is after Child3")
Else
    Console.WriteLine("Child5 is not after Child3")
End If

This example produces the following output:


Child5 is after Child3
