The following example creates two XML trees, and then uses this method to add an XElement object to one of them. It also adds the results of a LINQ query to the XML tree.


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>

xmlTree.Add(New XElement("NewChild", "new content"))
xmlTree.Add( _
    From el In srcTree.Elements() _
    Where CInt(el) > 3 _
    Select el _
)
' Even though Child9 does not exist in srcTree, the following statement will not
' throw an exception, and nothing will be added to xmlTree.
xmlTree.Add(srcTree.<Child9>)
output.Append(xmlTree)
output.Append(Environment.NewLine)


OutputTextBlock.Text = output.ToString()
