Quickies for XML

---

General

• Reading property lists from XML [permalink]
  This will read property lists in XML (or any of the other property list formats:)

      NSData *data = // get NSData from somewhere, like NSFileManager
      if (data) {
          myRootObject = [NSPropertyListSerialization
                             propertyListFromData: data
                             mutabilityOption: NSPropertyListMutableContainers
                             format: nil
                             errorDescription: nil];
      }
  

  For the mutability options of the resulting object, you can also use NSPropertyListImmutable and NSPropertyListMutableContainersAndLeaves

• Saving property lists as XML [permalink]
  You can save any of the "property list" classes (NSDictionary, NSArray,NSNumber, NSString, NSData) as XML like this:

      NSData *data;
      data = [NSPropertyListSerialization
                 dataFromPropertyList: notes
                 format: NSPropertyListXMLFormat_v1_0
                 errorDescription: nil];

  Then write out the data using NSFileManager, or whatever other mechanism you wish.
