[Java] Trasformare un xml usando xsl

[Reiuky]

Buongiorno a tutti.

Ho trovato questo codice su una guida on-line, che dovrebbe trasformare un file .xml usando un .xsl associato in un (credo) .html

Ho provato a implementarlo, ma il file risultante mi resta vuoto. Siccome non ho praticità con queste classi, probabilmente sbaglio qualcosa (che so, gli devo dire di scrivere / salvare il file prima di uscire), ma non so come. Nè so se l'errore è li...

Help ^_^
