How do I match . . . Thank you both very much!

[plz_reply_to_group]

Dang, those are both good ideas! Now that I have taken a little break
from what i was doing, I can see that I was not thinking too clearly
about what I was trying to do. I was thinking in terms of "regular
expressions", not strings! I was almost going to resort to reversing the
string, then matching the '/', clipping off the file name, then
reversing it again, or using a while loop to match each occurance. Both
seemed inelegant. 
 
Thanks!
