If you want the XML file to be indented, then just insert these lines in your existing code:
XmlTextWriter writer = new XmlTextWriter(proNavnTb.Text + ".xml",Encoding.UTF8);
writer.Formatting = Formatting.Indented; writer.Indentation = 4; writer.WriteStartDocument();

Hi,
try this
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb);
writer.WriteStartDocument();
writer.WriteStartElement("PRODUKT");
writer.WriteStartElement("NAVN");
writer.WriteString(proNavnTb.Text);
writer.WriteEndElement(); //NAVN
writer.WriteStartElement("NUMMER");
writer.WriteString(proNrTb.Text);
writer.WriteEndElement(); //NUMMER
writer.WriteStartElement("MÆRKE");
writer.WriteString(proBrandTb.Text);
writer.WriteEndElement(); //MÆRKE
writer.WriteStartElement("PRIS");
writer.WriteString(proPrisTb.Text);
writer.WriteEndElement(); //PRIS
writer.WriteStartElement("SPEC");
writer.WriteString(proBeskrivTb.Text);
writer.WriteEndElement(); //SPEC
writer.WriteEndElement(); //PRODUKT
writer.WriteEndDocument();
var myXmlString = sb.ToString()
