Remove namespace xmlns:kk="kk" from XML data

Hi I have created an XML file, however 1 of the nodes is adding a namespace reference and I cant seem to remove it. Only adds to first element/node.

Code

XmlDocument doc =doc.Load(System.Configuration.ConfigurationManager.AppSettings["doctemploc"]);

XmlElement Blaett = doc.CreateElement("kk:Blaett","kk");
 XmlAttribute numbber = doc.CreateAttribute("number");

Blaett.Attributes.Append(numbber);

What I have tried:

nummer.RemoveAttribute("xmlns:kk");
nummer.Attributes().Where(a => a.IsNamespaceDeclaration).Remove()
nummer.Attributes("xmlns").Remove();

If you don't want the namespace in the output, then don't specify a namespace.

Replace:

XmlElement Blaett = doc.CreateElement("kk:Blaett","kk");

with:

XmlElement Blaett = doc.CreateElement("Blaett");

NB: Is it not valid for an XML document to use a namespace prefix without declaring the namespace.

I'd say: it's pretty obvious...

I tried this but it just moved the xmlns:kk="kk" down to the next element and repeated it again.

When this is removed by hand (from <Blaett numbber="311" xmlns:kk="kk"> to <Blaett numbber="311">) it validates against XSD

Because you're specifying the namespace on the next element (which you didn't show in your question).

If you don't want the namespace in the output, then don't specify the namespace when you create the elements!

Your good....I tried that also, removing the doc.CreateElement("kk:Blaett","kk") and subsequent ones.

It failed to validate against the XSD... it needs namespace a front ie <kk:Blaett.

Its been frustrating trying to get it working...

If it needs the namespace, then why are you trying to remove it?!

An XML file with a prefixed name that doesn't correspond to a namespace declaration is not valid.

This article here looks close to what I want...I just need to remove xmlns:kk="kk" from line <Blaett numbber="311" xmlns:kk="kk">
