Add xmlns to node

hi

im using the following

Dim _xdoc As New Xml.XmlDocument
Dim _xmlString As New System.Text.StringBuilder

_xmlString.Append("<configuracao'")
_xmlString.Append("<oracle>")
_xmlString.Append("<utilizador>tony</utilizador>")
_xmlString.Append("<palavrapasse>tony</palavrapasse>")
_xmlString.Append("<instancia>MYINSTANCE</instancia>")
_xmlString.Append("<enderecoservidor>10.1.1.1</enderecoservidor>")
_xmlString.Append("</oracle>")
_xmlString.Append("</configuracao>")
_xdoc.LoadXml(_xmlString.ToString())

Dim xmldecl As Xml.XmlDeclaration
xmldecl = _xdoc.CreateXmlDeclaration("1.0", "Windows-1252", "yes")

Dim root As Xml.XmlElement = _xdoc.DocumentElement
_xdoc.InsertBefore(xmldecl, root)

_xdoc.Save("CONFIGURACAO.xml")

this is working fine for me and it produces this document :

<?xml version="1.0" encoding="Windows-1252" standalone="yes" ?>
<configuracao>
<oracle>
<utilizador>tony</utilizador>
<palavrapasse>tony</palavrapasse>
<instancia>MYINSTANCE</instancia>
<enderecoservidor>10.1.1.1</enderecoservidor>
</oracle>
</configuracao>

i would like to have the xmlns add to the first node

<?xml version="1.0" encoding="Windows-1252" standalone="yes" ?>
<configuracao xmlns="urn:OECD:StandardAuditFile-Tax:PT_1.01_01">
<oracle>
<utilizador>tony</utilizador>
<palavrapasse>tony</palavrapasse>
<instancia>MYINSTANCE</instancia>
<enderecoservidor>10.1.1.1</enderecoservidor>
</oracle>
</configuracao>

Write out an XmlNode object with your Xml, then use the InsertBefore/After methods on the XmlDocument object.
