XSL and ASP

it might have been answered before

but i want to create an xsl that changes xml into an aspx file, i therefore
want to add code such as:

<asp:button..

into my xsl file. 

i use an aspx file to get the xml and xsl file and carry out the
transformation but when i run the file the server gives me an error that it
doesn't recognise the namespace asp. i tried to enclose the tag in:

<xsl:text disable-output-escaping...
but the same error crops up. what am i doing wrong, what else can i do?
