my ($data) = $test_s =~ /(\[(.+)\]/;
I think it contains a "(" that shouldn't be there (after =~ /).
The code above assumes you want what is between the first and last
brackets in $test_s. If the string contains more than one set of
brackets you may want to say this instead:
my ($data) = $test_s =~ /(\[(.+?)\]/;
That ( is till there but it was surely copied by mistake, however in this
case the regexp should also use a /g modifier:
my ($data) = $test_s =~ /\[(.+?)\]/g;
Understand and works fine..
I would assume either below would be also true
($data) = $data =~ /\[(.+)\]/;
and
@data = $data =~ /\[(.+)\]/;
Use .+? and use the /g modifier.
.+ would match everything from the first [ to the last ] so you will have a
single element in @data.
.+? would match non-greedy - everything from the first [ to the next ] so
you would have more elements in @data, but only if you use /g, because
otherwise @data would contain only the first element.
