Examples

The following example uses a LINQ query to create an IEnumerable<T> of XElement, which it then passes to this method. This adds the results of a query to the tree in the desired location.

XElement srcTree = new XElement("Root",  
    new XElement("Element1", 1),  
    new XElement("Element2", 2),  
    new XElement("Element3", 3),  
    new XElement("Element4", 4),  
    new XElement("Element5", 5)  
);  
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)  
);  
XElement child1 = xmlTree.Element("Child1");  
child1.AddAfterSelf(  
    from el in srcTree.Elements()  
    where (int)el > 3  
    select el  
);  
Console.WriteLine(xmlTree);

Dim srcTree As XElement = _  
    <Root>  
        <Element1>1</Element1>  
        <Element2>2</Element2>  
        <Element3>3</Element3>  
        <Element4>4</Element4>  
        <Element5>5</Element5>  
    </Root>  

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

Dim child1 As XElement = xmlTree.<Child1>(0)  
child1.AddAfterSelf( _  
    From el In srcTree.Elements() _  
    Where CInt(el) > 3 _  
    Select el _  
)  
Console.WriteLine(xmlTree)

This example produces the following output:

XML

<Root>  
  <Child1>1</Child1>  
  <Element4>4</Element4>  
  <Element5>5</Element5>  
  <Child2>2</Child2>  
  <Child3>3</Child3>  
  <Child4>4</Child4>  
  <Child5>5</Child5>  
</Root>

Examples

The following example uses this method to add an element into the tree.

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)  
);  
XElement child1 = xmlTree.Element("Child1");  
child1.AddAfterSelf(  
    new XElement("NewChild", 10)  
);  
Console.WriteLine(xmlTree);

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

Dim child1 As XElement = xmlTree.<Child1>(0)  
child1.AddAfterSelf(New XElement("NewChild", 10))  
Console.WriteLine(xmlTree)

This example produces the following output:

XML
