[AS CS5] Sorting out multiple nested objects

Question

I have documents where we have labelled frames for scripting. Some of our artist have pasted these labelled frames inside of duplicates of the original labelled frame, or they have group multiple objects, and pasted then into (using **paste into) the labelled box.
This is giving me a big headache when I run the script.
What I have in the document is like this:
Labelled Box < Labelled Box (inside)
or
Labelled Box < group (inside) < Labelled Box1, Labelled Box2 (inside)
or
Labelled Box1, Labelled Box2 (not grouped, not inside of anything else, just 2 instances)
I am trying to get every page item of all page items whose label is "theLabel". This has the result of returning me a list of 2 or more items. If the box has boxes pasted into, I only need the top level item. If there is a group and sub items, I still only want the top object. In the last instance, since there are no items pasted into, I want the top level items, and this can be 2 or more items.
Is there a way of trying to see if one item is inside of one another? I can see that every item has a parent item, and the parent of example 1 is the frame. So I could ask one frame if its parent is the other one, and filter one out of my selection. The parent of each sub-item of example 2 is the group, not the main frame, and I can't seem to see how to ask if a group is inside of another frame. Since my return value on "every object whose label is..." returns items, not a group, how do I find out what the parent is? I tried to coerce a parent value to a string in order to just do some string comparisons but that didn't seem to work.

Answer 1

You don't need the Disk Image. Assuming you have copies of the Libraries you can delete them all.
For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.
