Dealing with list created by STRSPLIT? [message #76194]

I have an array of full-path filenames from which I need to extract
some substrings. The array consists of a large number of strings of
the form

diskname/maindir/subdir1/subdir2/subdir3/filename
diskname/maindir/subidr1/subdir2/subdir3/filename etc.

The lengths of the subdirXs can be different. What I wanted to do was
create some arrays the elements of which would be the subdirXs. I
thought this would be simple now that STRSPLIT allows arrays as
input. I had the array of n filenames in a string array and I used

splitnames = STRSPLIT(filenames, '/', /EXTRACT).

The result 'splitnames' is a list with n elements and each element is
of the form

diskname maindir subdir1 subdir2 subdir3 filename as it should be.
Each element is a string array.

What I can't seem to figure out is how to now extract one of these
terms from the list element. That is, I'd like to end up with arrays
that have the n subdir2s (for example). I've tried using the
LIST::TOARRAY () feature but this fails for some mysterious reason
with the message

IDL> namearray=splitnames.ToArray()
% LIST::TOARRAY: Unable to convert to type STRING: Element 798
% Error occurred at: LIST::TOARRAY
% $MAIN$
% Execution halted at: $MAIN$

Element 798 is no different from any of the elements in the list, by
the way, but this is not the real problem (at least I don't think it
is)

There must be an easy way to do this; I'm not seeing it. Any help
would be much appreciated.
