What happened when I used the code -- $hello =~ s/^(.+)$/<s>\1<\/s>/gis;
-- is that is properly marked <s> and the beginning of the sentence and </s> at the end of the sentence, but then it only worked for one sentence. Any suggestions on getting <s> to appear at the beginning of every sentence and </s> to appear at the end of every sentence for more than one sentence?
