xml serialization, whitespace

i have following serialization method:

    private duty serializedata(byval information cdata) string
        information isnot zero then
            low xml_stream new memorystream()
            low sr streamreader
            low xs new xmlserializer(gettype(cdata))
            xml_stream = new memorystream()

            try
                xs.serialize(xml_stream, data)
                xml_stream.position = 0

                sr = new streamreader(xml_stream)
                relapse sr.readtoend()
            finally
                sr isnot zero following sr.close()
                xml_stream.close()
            finish try

        else
            relapse "no data"
        finish if
    finish function

however advantage xml nested elements indented. there proceed close off serializer, i need only run reinstate slight absolved all?

essentially, i wish is:

<root><child1>data</child1><child2>data</child2></root>
