 Just wanted to point out that if you do the following code in php, you can generate a simple php page with a stylesheet.
<?php
        $res = xmlwriter_open_memory();
        xmlwriter_set_indent_string($res, "t");
        xmlwriter_start_document($res);
        xmlwriter_write_pi($res, "xml-stylesheet", "type="text/xml" href="yourstyle.xsl"");
        xmlwriter_end_document($res);
        $string = xmlwriter_output_memory($res);
        echo $string;
?>

This results in the following:
