    </Root>

Dim sb As StringBuilder = New StringBuilder()
Dim xws As XmlWriterSettings = New XmlWriterSettings()
xws.OmitXmlDeclaration = True
Using xw As XmlWriter = XmlWriter.Create(sb, xws)
    Dim dstTree As XStreamingElement = New XStreamingElement("NewRoot", _
                            From el In srcTree.Elements() _
                            Where el.Value = 5 _
                            Select <DifferentChild><%= el.Value %></DifferentChild> _
                        )
    dstTree.Save(xw)
End Using
output.Append(sb.ToString())
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
XElement srcTree = new XElement("Root",
                       new XElement("Child", 1),
                       new XElement("Child", 2),
                       new XElement("Child", 3),
                       new XElement("Child", 4),
                       new XElement("Child", 5)
                   );

StringBuilder sb = new StringBuilder();
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
using (XmlWriter xw = XmlWriter.Create(sb, xws))
{
    XStreamingElement dstTree = new XStreamingElement("NewRoot",
                            from el in srcTree.Elements()
                            where (int)el == 5
                            select new XElement("DifferentChild", (int)el)
                        );

    dstTree.Save(xw);
}
output.Append(sb.ToString() + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
