Here's a regex that should get you started:
/("[^"]*"|[^\s"]+)/g;
This regex makes two following assumptions: a word is a sequence of non-whitespace, non-quote characters, and a quotation cannot contain embedded quotes.
Here's an example:
sub split_text {
$_[0] =~ /("[^"]*"|[^\s"]+)/g;
}
my $text = 'The dog said "Hi, how are you?" I laughed.';
my @pieces = split_text($text);
print "$_\n" for @pieces;
__END__
The
dog
said
"Hi, how are you?"
I
laughed.
