How to display XML in webform?

[someTimeOnly]

What's wrong here. Why it's not being displayed with label control.

private void Page_Load(object sender, System.EventArgs e)
{
XmlDocument doc = new XmlDocument();
string xmlData = "<bookxmlns:bk='urn:samples'></book>";
doc.Load(new StringReader(xmlData));

Label1.Text = doc.OuterXml.ToString();
}

even

Label1.Text = xmlData;

is not displaying.

Are you sure that "<bookxmlns:bk='urn:samples'></book>" is good XML
