How to make XMLDOMDocument include the XML Declaration?

Question

When an XMLDOMDocument saves itself, how can i get it to include the XML Declaration, e.g.:

You need to use a MXXMLWriter60, instead of saving it directly. Sorry I don't have a C# example, but here is the VB.Net equivalent. See IMXWriter for details.

' Create and load a DOMDocument object.

Dim xmlDoc As New DOMDocument60
xmlDoc.loadXML("test1test2")

' Set properties on the XML writer - including BOM, XML declaration and encoding

Dim wrt As New MXXMLWriter60
wrt.byteOrderMark = True
wrt.omitXMLDeclaration = False
wrt.encoding = "US-ASCII"
wrt.indent = True

' Set the XML writer to the SAX content handler.

Dim rdr As New SAXXMLReader60
Set rdr.contentHandler = wrt
Set rdr.dtdHandler = wrt
Set rdr.errorHandler = wrt
rdr.putProperty "http://xml.org/sax/properties/lexical-handler", wrt
rdr.putProperty "http://xml.org/sax/properties/declaration-handler", wrt

' Now pass the DOM through the SAX handler, and it will call the writer

rdr.parse xmlDoc

' Let the writer do its thing

Dim iFileNo As Integer
iFileNo = FreeFile
Open App.Path + "\saved.xml" For Output As #iFileNo
Print #iFileNo, wrt.output
Close #iFileNo
