Gets a comparer that can compare the relative position of two nodes.

Property Value

XNodeDocumentOrderComparer

An XNodeDocumentOrderComparer that can compare the relative position of two nodes.

Examples

The following example creates an XML tree with some elements. It then creates a List<T> of XNode that contains some elements from the XML tree at random. It sorts the list, using this property to retrieve a XNodeDocumentOrderComparer, which implements the System.Collections.IComparer and System.Collections.Generic.IComparer<T> interfaces.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XElement("Child5", 5)  
);  

List<XNode> nodeList = new List<XNode>();  
nodeList.Add(xmlTree.Element("Child5"));  
nodeList.Add(xmlTree.Element("Child3"));  
nodeList.Add(xmlTree.Element("Child1"));  

// Sort nodes in document order.  
nodeList.Sort(XNode.DocumentOrderComparer);  

foreach (XElement el in nodeList)  
    Console.WriteLine(el);  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
            <Child4>4</Child4>  
            <Child5>5</Child5>  
        </Root>  

Dim nodeList As List(Of XNode) = New List(Of XNode)()  
nodeList.Add(xmlTree.Element("Child5"))  
nodeList.Add(xmlTree.Element("Child3"))  
nodeList.Add(xmlTree.Element("Child1"))  

' Sort nodes in document order.  
nodeList.Sort(XNode.DocumentOrderComparer)  

For Each el In nodeList  
    Console.WriteLine(el)  
Next

This example produces the following output:

<Child1>1</Child1>  
<Child3>3</Child3>  
<Child5>5</Child5>

Remarks

This property is primarily used internally for implementing the InDocumentOrder extension method. The recommended approach is to use that extension method instead of using this property directly.
