Withoug being sure, my guess is that the XML will take some standard
references from W3 just like being in HTML in that code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d">

Just an idea.

I tried inheriting XMLSerializer and overriding the "Serialize"
procedure... but it doesn't seem to execute. Do you if there is anything
special to do when overriding XMLserializer?

Thanks!

RE: XML Serialization - Remove XML-instance namespace?

If you want to get rid of both - XML declaration and those namespace
attributes you can create your XmlWriter with explicit settings (the
namespace attributes were already discussed above):

// source: object instance to serialize
// file: target file name to write the XML to
void Serialize(objec t source, string file)
{
XmlWriterSettin gs settings = new XmlWriterSettin gs();
settings.OmitXm lDeclaration = true;
settings.Indent = true;

XmlSerializerNa mespaces namespaces = new XmlSerializerNa mespaces();
namespaces.Add( string.Empty, string.Empty);

using (XmlWriter writer = XmlWriter.Creat e(file, settings))
{
XmlSerializer serializer = new XmlSerializer(s ource.GetType() );
serializer.Seri alize(writer, source, namespaces);
}
}

RE: XML Serialization - Remove XML-instance namespace?

Use the following code to get rid of the XML declaration and the
namespace declaration attributes (the latter has been suggested above
already) - explicit settings for the writer do the trick:

// source: source object instance to serialize
// target: target file name to write the XML to
void Serialize(objec t source, string file)
{
XmlWriterSettin gs settings = new XmlWriterSettin gs();
settings.OmitXm lDeclaration = true;
settings.Indent = true;

using (XmlWriter writer = XmlWriter.Creat e(file, settings))
{
XmlSerializer serializer = new XmlSerializer(s ource.GetType() );

XmlSerializerNa mespaces namespaces = new
XmlSerializerNa mespaces();
namespaces.Add( string.Empty, string.Empty);

serializer.Seri alize(writer, source, namespaces);
}
}
