Yes, the PropertyValue array contains the whole
"File" menu. The 
"ItemDescriptorContainer" provides you the next
level of menu items.

OOo works with an indirection between command url and label.
The label 
is retrieved on runtime from configuration files using the
command url 
as a key. Therefore you won't get any label information for
built-in 
commands from the settings. If you want to identify a single
menu item, 
you should always use the command url, because the label
would be 
language dependent.

XIndexAccess provides you with the following functions.

published interface XIndexAccess:
com::sun::star::container::XElementAccess
{
   /** returns  the number of elements in this container.*/
   long getCount();
	
   // DocMerge from idl: method
   com::sun::star::container::XIndexAccess::getByIndex
   /** returns  the element at the specified index.
				
     param Index	
	specifies the position in the array. The first index is 0.
   */
   any getByIndex( [in] long Index )
			raises( com::sun::star::lang::IndexOutOfBoundsException,
					com::sun::star::lang::WrappedTargetException );
};

But I think I need a XIndexContainer or again a
> PropertyValue[]. 
Why? You can call getByIndex and retrieve the next
sequence< 
PropertyValue >. Where is the problem?

How can I get it?
Just call getByIndex() using XIndexAccess. If you want to
change 
entries, you have to query the interface for
XIndexContainer.

To make it clear:

oMenuBarSettings = oMenuBar.getSettings(true)
The index container provides the following information
   0    1        n
|File|Edit|...|Help|

PropertyValue[] oFileMenu = oMenuBarSettings.getByIndex(0)
|"Label"|
The label of the menu item, if set by the user. Normally
empty.
|"CommandURL"|
The command which should be dispatched.
|"ItemDescriptorContainer"|
The next level of the file menu (XIndexAccess) =>
|Newpen|Recen
t 
Documents|---|...

I think you should read some documentation in the
Developer's Guide to 
better understand UNO based containers and the UNO interface
concept.
