Dim elements = From el In xmlTree.Elements _
               Where el.Value <= 3 _
               Select el

For Each el In elements
    output.Append(el)
    output.Append(Environment.NewLine)
Next

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
XElement xmlTree = new XElement("Root",
    new XElement("Child1", 1),
    new XElement("Child2", 2),
    new XElement("Child3", 3),
    new XElement("Child4", 4),

IEnumerable<XElement> elements =
    from el in xmlTree.Elements()
    where (int)el <= 3
    select el;
