PowerShell: Ein schneller Versuch, ADMX zu parsen

Hier ein bißchen Code, um alle Einstellungen aus ADMXen inklusive Registry-Pfad und -Typ zu exportieren. Ein paar Typen könnten noch fehlen …

Achtung! In Zeilen 10 und 11 frißt der Syntax Highlighter den Typ (quadratische Klammer auf)xml(quadratische Klammer zu) unmittelbar vor der runden Klammer. Noch weiß ich nicht, wie ich ihn überredet bekomme, das anzuzeigen. Bis dahin hier der Quelltext zum Download: admx_parser
