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()
