Hi Ab, but I have tested the following code, which were giving me the same test results on many test cases:
if ($str =~ /_test(?>\s+)(?!<)/) { print "test ok\n" }
if ($str =~ /_test(?:\s+)(?!<)/) { print "test ok\n" }

Could you please tell me as why the /_test(?:\s+)(?!<)/ is wrong? I want to learn. Thanks!
