Re: Regular expression...

[prasadbabu]

Here is one way to do it.

$string ='
some another lines
=begin
some lines
some lines
=end
some another lines...';

while ($string =~ /(?:(?:^|\n)=begin)((?:(?!\n=end).)*)\n=end/gs){
    
    print "$1\n";
    
}

output:
=======

some lines
some lines

Updated: included '\n' before =end.
