I swiftly got it as an NSData, but now i'm trying to figure out how to get it out of that.

i try using this: NSPropertyListSerialization method:
+ (id)propertyListFromData:(NSData *)data mutabilityOption:(NSPropertyListMutabilityOptions)opt format:(NSPropertyListFormat *)format errorDescription:(NSString **)errorString


NSData *data = [NSData dataWithContentsOfFile:[@"~/Music/iTunes/iTunes Music Library.xml" stringByStandardizingPath]];

NSDictionary *plist = [NSPropertyListSerialization
propertyListFromData:data mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:NSPropertyListXMLFormat_v1_0
errorDescription:@"blah"];


The third parameter is a NSPropertyListFormat *, not NSPropertyListFormat, as shown in the method declaration. Also the fourth parameter is a NSString **, not an NSString *.

NSPropertyListFormat theFormat;
NSString *theError;

NSDictionary *plist = [NSPropertyListSerialization
propertyListFromData:data
mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:&theFormat
errorDescription:&theError];

The format is returned to you, in case you want to preserve it because you're going to modify and rewrite the file. The error string is also returned by reference. Either of these parameters can be NULL instead of a pointer to storage, if you don't want the value.
