Deleting .zipped files based on XML updates? (Hyperspin)

[tommytutone]

I, like I'm sure many of you, have deleted several fruit machines and games that cannot be played on my cabinet that I am close to finishing up.  To get rid of these games from appearing in Hyperspin, I am updating the mame.xml file that lists the games and deleting the records of those unplayable and unwanted from there.

What I would like to do from there, however, is find an automated way to reconcile the .z7 ROMs with the .xml file, deleting all of the ones I do not want.  My hard drive space is tight and as such, I'm using an external hard drive to host the ROMs (yes, I know I can install a new hard drive, but would rather not if this will work) and would hopefully clear up enough space to move everything over to the smaller internal hard drive.

Assuming any of what I wrote makes sense to anyone else, is there an automated solution to cleaning up the junk, so to speak?

If you have a mac, you could create an AppleScript to do this. Read and store both XML variables as hashes. If the rom zip does not exist in the revised XML, remove the file with corresponding name.
