I'm trying to do some scripting that edits a binary plist file. The plist describes the objects contained in a DVD studio pro file. It appears that a text box in DVD studio pro is encoded in the plist as hex data that describes the text string along with its formatting. I can't seem to figure out how to understand this data. Ideally, I'd like to be able to alter the text string but not the formatting. The following seems to describe a text box that says "Menu title here". There are two hex strings, one with the key called "dictionary" and the other called "string"; both are CFData. Any ideas how I can parse this or convert this into a format that I can edit directly? I've been playing around with writing a little converter in cocoa, but no luck yet.
