Different views of the same XML file

Good morning,
	I want different views of the same XML
file. I.e. I want to apply different XSL on the same
XML file. How can I do it? I know how to apply
the XSL to the XML adding the line:

<?xml-stylesheet type="text/xsl" href="firstview.xsl"?>

to the XML file. If I do this, I have to copy the
XML file twice and replace that line with another one
like:

<?xml-stylesheet type="text/xsl" href="secondview.xsl"?>

This does not make sense at all. there should be a simpler
and elegant way to do it.

Please let me know,
	best regards,
		Marco Zennaro
