XNode.IsAfter Method
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)
Parameters
- node
- Type: System.Xml.Linq.XNode
The XNode to compare for document order.
Return Value
Type: System.Booleantrue 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.
XElement xmlTree = new XElement("Root", new XText("Text content."), new XElement("Child1", "child1 content"), new XElement("Child2", "child2 content"), new XElement("Child3", "child3 content"), new XText("More text content."), new XElement("Child4", "child4 content"), new XElement("Child5", "child5 content") ); XElement child3 = xmlTree.Element("Child3"); XElement child5 = xmlTree.Element("Child5"); if (child5.IsAfter(child3)) Console.WriteLine("Child5 is after Child3"); else Console.WriteLine("Child5 is not after Child3");
This example produces the following output:
Child5 is after Child3
