your stylesheet not output html rather xhtml fragment, , in way (with qualified names) need serve application/xml browser (like mozilla, opera, safari, ie 9, not ie 6-8) understands content type.

so make sure like

  header('content-type: application/xml'); 

before sending content browser. or drop xhtml namespace , prefixes result elements, xslt stylesheet outputs html fragment many more browsers can parse , understand text/html , render want.
