RSS Script

Hallo iedereen,

K had een vraagje. Om op mijn website een RSS feed weer te geven gebruik ik onderstaand script. Alleen ik vroeg mij af hoe ik erover kan zorgen dat wanneer je op de link klikt(die de RSS feed voorziet), deze in een nieuw scherm opent, oftewel blank.

Alvast bedankt!

Very simple and basic yet powerful! 
Works for standard RSS version 0.91, 1.0 and 2.0 
You are free to use this script, as long you remember who made this :-)
