Net 2.0

I'm using xml to store company configuration settings in a BLOB database 
field.

I create an xPathNavigator like this:

Dim doc As XmlDocument = New XmlDocument

Dim strXml As String = (-read the xml string from the db)

Dim sr As New System.IO.StringReader(strXml)

doc.Load(sr)

xnav = doc.CreateNavigator

And then use the xnav to read and set fields from the application.

When I save the xml string back to the database, I loose the xml declaration 
"<?xml version="1.0" encoding="UTF-8" ?>" with xnav.outerxml.

Is there some way to get the xml string WITH the xml declaration?

The XPath data model does not know about XML declarations so the 
XPathNavigator does not have them. With .NET the DOM model contains an 
XML declaration so you should use doc.OuterXml (or use the Save method 
of the XmlDocument doc) if you want an XML declaration.

Thanks Martin,

Perhaps I will leave it as it is without the xml declaration since it is 
only for internal use and there seems to be no problem reading/writing to 
the saved document.
