For more information about the valid content of an XDocument, see Valid Content of XElement and XDocument Objects in the .NET Framework documentation.

The following example creates a document, and then adds a comment and an element to it. It then composes another document using the results of a query.


Dim output As New StringBuilder
Dim srcTree As XDocument = _
    <?xml version="1.0" encoding="utf-8" standalone="yes"?>
    <!--This is a comment-->
    <Root>
        <Child1>data1</Child1>
