parsing of string using regex in perl

Question

DESCR: "10GE SR"

i need match this above part which is part of my rest of the string. Im using regex in perl. i tried

if ($line =~ /DESCR: \"([a-zA-Z0-9)\"/) { 
   print "$1\n";
}

$str = 'DESCR: "10GE SR"';

if ($str =~ /DESCR: \"([a-zA-Z0-9\s]+)\"/) { 
    print "$1\n";
}

Take a look, this pattern can match double quoted in string:

if ($line =~ /DESCR: \"((?:[^\\"]|\\.)*)\"/) { 
   print "$1\n";
}

It may be simpler:

if ( $line =~ /DESCR: "([^"]+)"/ ) { 
   print "$1\n";
}
