matching between two strings	Can't Post

I have a file which contains numerous datasets having the following format, see below:
I need to extract the data between Final graph set matrix and PLUTO4 finished each time it is present in the file (so need some sort of loop).
I have the following pattern for matching the data:

Code

/([A-Z]\s\d+,\s\d+\(\s*\d+\))/g

Also I need each data seperated by a title or new line
Can anyone help

Final graph set matrix
----------
C 1, 1( 9)
----------
C 2, 2(11) C 1, 1( 4)
----------
C 2, 2(18) C 1, 2(11) C 1, 1( 9)
[R 2, 2( 8)]
----------
C 1, 2(11) C 2, 2(18) C 2, 2(11) C 1, 1( 4)
[R 2, 2(18)]
PLUTO4 finished

Final graph set matrix
----------
C 1, 1( 4)
----------
C 2, 2(18) C 1, 1( 4)
[R 2, 2(18)]
PLUTO4 finished

Final graph set matrix
----------
C 1, 1( 4)
----------
C 2, 2(18) C 1, 1( 4)
[R 2, 2(18)]
----------
C 2, 2(11) C 2, 2(11) C 1, 1( 9)
----------
C 2, 2(11) C 2, 2(11) C 2, 2(18) C 1, 1( 9)
[R 2, 2( 4)]
PLUTO4 finished

You can do something like this to get your data into a useable data structure.

Code

my (@sets, @set); 
 
my  $in_record; 
while (<INPUT>)  { # or whatver your filehandle is called 
  if (/^Final graph set matrix$/) { 
    $in_record = 1; 
    @set = (); 
    next; 
  } 
  if (/^ PLUTO4 finished$/) { 
    $in_record = 0; 
    push @sets, [ @set ]; 
  } 
  next if /^-+$/; # skip separator lines 
 
  push @set, $_ if in_record; 
}

At the end of this code you'll have an array called @sets. Each element in this array contain one of your data sets. Each element is actually a reference to another array which contains all of the lines of data in the set.

Don't really know what you want to do after that as I don't understand your description.
