As a side note, NetWallah's solution calls perl from the command line -- if you wanted to use it in your code, do this:

  while ($desc =~ /\[(.*?)\]/g)
  {
  }
  $org = $1 or '';

or 
  $desc =~ s/\[(.*?)\]//g;
  $org = $1 or '';

[download]

The regex used essentially matches all data within brackets, but only saves the last one. The first example uses m//, and must therefore be run through a loop as the /g modifier merely saves the place where the previous regex match ended.

The second option will destroy the string stored in $desc, but does not require the loop.
