Thanks for the help, Shawn.
Look at this code:
my @data = ( 'Twinkle twinkle little star
How I wonder what you are
Up above the world so high
Like a diamond in the sky.
123
Twinkle twinkle little star
How I wonder what you are');
my $rx1 = qr{ world.*diamond }imx;
my $rx2 = qr{ what.*world }mix;
my $rx3 = qr{ little\D*wonder }imx;
my $rx4 = qr{ high.*like }imx;
my @regex = ($rx1, $rx2, $rx3, $rx4);
my $regx = join ("|", @regex);
my @matches = map { tr/\n//d; /($regx)/g } @data;
print 'result: ', Dumper \...@matches;
and the output is:
result: $VAR1 = [
'little starHow I wonder',
'what you areUp above the world',
'highLike',
'little starHow I wonder'
];
The string that matches the regex 'world.*diamond' wasn't picked by the above
expression. It looks like it was not picked because some part of the string was
already picked by another regex. How can I get the expression pick that as well
so the output would be like below:
result: $VAR1 = [
'little starHow I wonder',
'what you areUp above the world',
'world so highLike a diamond',
'highLike',
'little starHow I wonder'
];
