Hi Again, You guys have been so helpful lately, I thought I would ask for some advice on a piece of code I have constructed. My objective is to consolidate all the unique elements of my array. My current elements are:

  CHILD: Topology/IPClassA
  CHILD: Topology/IPClassA/Device
  CHILD: Topology/IPClassA/Device/log_ratio
  CHILD: Topology/IPClassA/Device/poll_interval
  CHILD: Topology/IPClassA/Device = 2
  CHILD: Topology/IPClassA/Device = 2/poll_interval
  CHILD: Topology/IPClassA/Device = 2/is_managed
  CHILD: Topology/IPClassA/Device = 2/Port
  CHILD: Topology/IPClassA/Device = 2/Port/ifPhysAddress
  CHILD: Topology/IPClassA/Device = 2/Port/poll_interval
  CHILD: Topology/IPClassC
  CHILD: Topology/IPClassC/Device
  CHILD: Topology/IPClassC/Device/poll_interval
  CHILD: Location

Now as you can see the first element (Topology/IPClassA) is part of the second element so I would like to disregard that one, and continue this until I have an array of unique data. My desired result would look like this:

  CHILD: Topology/IPClassA/Device/log_ratio
  CHILD: Topology/IPClassA/Device/poll_interval
  CHILD: Topology/IPClassA/Device = 2/poll_interval
  CHILD: Topology/IPClassA/Device = 2/is_managed
  CHILD: Topology/IPClassA/Device = 2/Port
  CHILD: Topology/IPClassA/Device = 2/Port/ifPhysAddress
  CHILD: Topology/IPClassA/Device = 2/Port/poll_interval
  CHILD: Topology/IPClassC/Device/poll_interval
  CHILD: Location

Please note that order DOES matter and that the eighth element of the final array Topology/IPClassC/Device/) is the same as the first element.

I have tried such things as removing the child portion of the string and pushing them onto an array with the following code: 

  push (@foo, $_) unless ($seen{$_}++);

The eighth element doesn't make the array, due to the fact that it matches the second element
