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.

Dim output As New StringBuilder
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)
output.Append(xmlTree)
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
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
);
output.Append(xmlTree + Environment.NewLine + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
