Anyway to read a .plist from a firefox add-on?

Question

Is there a pre-existing XPCOM guy that will let me interrogate a .plist file from Javascript, or do I need to use nsIFile and parse the XML myself?

(For background, there is a version number in a directory structure I don't control that I need to read from a .plist in order to be future-proof.)

Answer 1

I don't know what a .plist is but I gather it's some sort of XML.

If you're parsing XML, don't use nsIFile directly, use this: Parsing and serializing XML. You might also like to use E4X.
