With the g modifier, what matched once is out of scope for another match.
But a loop can do it
Another solution is perl: by using a look-ahead an RE substitution with g modifier will do it.

For completeness, here it is:
The (?= ) is the look-ahead; hard to remember, I always consult this tutorial.
Because the look-ahead is not part of the match, it must be not restored in the substitution.
Perl(version >= 5) uses an extended regular expression: | means "or", must be \escaped.

Perl::Critic::Policy::RegularExpressions::RequireDotMatcUsertContributed Perl Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything(3)NAME
Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything - Always use the "/s" modifier with regular expressions.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
When asked what "." in a regular expression means, most people will say that it matches any character, which isn't true. It's actually
shorthand for "[^
]". Using the "s" modifier makes "." act like people expect it to.
my $match = m< foo.bar >xm; # not ok
my $match = m< foo.bar >xms; # ok
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
Be cautious about slapping modifier flags onto existing regular expressions, as they can drastically alter their meaning. See
<http://www.perlmonks.org/?node_id=484238> for an interesting discussion on the effects of blindly modifying regular expression flags.
