If the matching tags aren't nested, it can be done like so
my $string = "<S>yada yada yada</S>"; print "Yes! $1\n" if $string =~ m{<S>(.*?)</S>}; ### Here is an explanation of the regular expression use YAPE::Regex::Explain; print YAPE::Regex::Explain->new('<S>(.*?)</S>')->explain; __END__ The regular expression: (?-imsx:<S>(.*?)</S>) 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): ---------------------------------------------------------------------- <S> '<S>' ---------------------------------------------------------------------- ( group and capture to \1: ---------------------------------------------------------------------- .*? any character except \n (0 or more times (matching the least amount possible)) ---------------------------------------------------------------------- ) end of \1 ---------------------------------------------------------------------- </S> '</S>' ---------------------------------------------------------------------- ) end of grouping ----------------------------------------------------------------------
