Problem using asp:xml to run html code

[Brendan]

Hi
I have a problem when I use the asp:xml web control to
read an xml file containing other asp: web controls. It
works if I use HTML controls.

Example.
My xml file looks like this

<page xmlns:asp="http://www.w3.org/1999/XSL/Transform"
runat="server">
<form runat="server">
<h1>Hello World</h1>
<asp:Label id="Label1" Text="Label Control"
runat="server"/>
</form>
</page>

When I load this to an XML control, in the body of my
page, the label doesnt show, but the 'Hello World' does.

It works well with HTMLcontrols such as table, tr and td.

It seems to disregard controls beginning with 'asp:' e.g.
asp:label, asp:table, asp:tablerow, etc.

Anybody got a solution ?
