adding attribute to a xml element

[CSharper]

I need to set an atribute to an xml element, I know how to do it with
XElement.SetAtt ributeValue method. But What I am trying to do is, I
need to add a attribute with a namespace like the following
test:name="test er"
When I try to add, it fails with : not a valid character in attribute.
So my question is
How do I go about adding the new namespace to XDocument and also the
the attribute so that set attribute value doesn't fail.

Thanks you very much

Something like:

XNamespace ns = "urn:my-namespace";
XElement el = new XElement("Foo",
new XAttribute(XNam espace.Xmlns + "test", ns),
new XAttribute(ns + "name", "tester"));
string xml = el.ToString();

(example with a separate root element)

XNamespace ns = "urn:my-namespace";
XDocument doc = new XDocument(
new XElement("Foo",
new XAttribute(XNam espace.Xmlns + "test", ns),
new XElement("Bar",
new XAttribute(ns + "name", "tester"))) );
string xml = doc.ToString();

One quick question, right now with this it works, but by default the
program is creating a namepsace of 'p7', is there a way, I can force
the p7 to a different name say csharp?

Thanks.

It is creating an *alias* of p7 because you haven't added the xmlns
attribute to the root. Note that my example doesn't generate any p7,
p2, etc - unless I drop the line:
new XAttribute(XNam espace.Xmlns + "test", ns),

Include a similar line, aliasing your namespace as whatever (where
I've aliased as "test") and you should be sorted. If you have
problems, can you post a short but complete example? (since the code
works "as posted", we'd need to look at what is different...)

Thanks, I was missing the alias.
