Hi@All.
Das letzte mal das ich was programmiert habe ist schon über 6 Jahre her. Jetzt habe ich einen kleinen NewsRotator für meinen Kumpel programmiert. Seine Seite läuft unter XHTML und das ist neuland für mich...
Ich habe zwar versucht das Script anzupassen aber ich komme einfach nicht dahinter. Hier mal der bisherige Quellcode:
