The following example creates an element that contains child elements. It then gets the first child node of the parent element.

    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XElement("Child5", 5)  
);  
XNode firstNode = xmlTree.FirstNode;  
Console.WriteLine(firstNode);  
Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
            <Child4>4</Child4>  
            <Child5>5</Child5>  
        </Root>  

Dim firstNode As XNode = xmlTree.FirstNode  
Console.WriteLine(firstNode)  

This example produces the following output:

<Child1>1</Child1>
