This is what you have
use YAPE::Regex::Explain;
print YAPE::Regex::Explain ->new(
qr/\[b\]([^\[\/b\]]+)/
)->explain;
__END__
The regular expression:
(?-imsx:\[b\]([^\[/b\]]+))
matches as follows:
NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
\[ '['
----------------------------------------------------------------------
b 'b'
----------------------------------------------------------------------
\] ']'
----------------------------------------------------------------------
( group and capture to \1:
----------------------------------------------------------------------
[^\[/b\]]+ any character except: '\[', '/', 'b',
'\]' (1 or more times (matching the most
amount possible))
----------------------------------------------------------------------
) end of \1
----------------------------------------------------------------------
) end of grouping
----------------------------------------------------------------------
This is what you want
m{
\[b\]
(
[^\[]+
)
\[/b\]
}sixgs
.+? will work just fine in place of [^\[]+
