Top Forums Shell Programming and Scripting Parsing a txt file according to two different tags Post 302936143 by Walter Misar on Monday 23rd of February 2015 08:51:51 AM

If you want to parse matching {} you will need a parsing algorithm using a stack. On the other hand if you rely on nice formatting so you just want to extract stuff between curly braces found in the first column things are easier. The following perl script for example will split the input into several output files:

Code:
#!/usr/bin/perl

my $nr=0;
my $fh=undef;

while (<>) 
{ if ( m/^{/ )
  { open($fh, ">", "output" . $nr) or die "Can't open output file !";
  }
  elsif ( m/^}/ )
  { close($fh);
    $fh = undef;
    $nr++;
  }
  elsif ($fh)
  { print $fh $_;
  }
}
