Question

I need to add multiple namespaces to the xdocument with same address (C#)

<root xmlns:f="urn://xml.voodoo.net/vd/formating-1.0" xmlns="urn://xml.voodoo.net/vd/formating-1.0">
 <a:something>stuff and more stuff</a:something>
</root>

if i add using the below code.. it shows only xmlns:f

XNamespace defaultNS = "urn://xml.voodoo.net/vd/formating-1.0";
XNamespace f = "urn://xml.voodoo.net/vd/formating-1.0";


XElement rootElement = new XElement(defaultNS + "root",
new XAttribute(XNamespace.Xmlns + "f", f.NamespaceName),

how to show 2 namespaces?? is it even possible?

Answer 1

var doc = new XDocument(
    new XElement(defaultNS + "root",

        new XAttribute(XNamespace.Xmlns + "f", defaultNS),
        new XAttribute("xmlns", defaultNS),
        new XElement(defaultNS + "something",
            new XAttribute(XNamespace.Xmlns + "f", defaultNS), "stuff and more stuff")
            )
    );

Desired output:

<root xmlns:f="urn://xml.voodoo.net/vd/formating-1.0" xmlns="urn://xml.voodoo.net/vd/formating-1.0">
  <f:something xmlns:f="urn://xml.voodoo.net/vd/formating-1.0">stuff and more stuff</f:something>
</root>
