i have following: str = "hello world. today wednesday" matchedterms matchedterms contains data so: > "world" > "word, is" what update str so: "hello <b>world</b>. today <b>is</b> wednesday" what right way in ruby/rails update string given matchedterms? thanks the string#gsub method takes block can make pretty easy (and should more efficient writing iterator/loop). here's how i'd go this: matched_terms = ["world", "is"] pattern = regexp.new(matched_terms.join("|"), regexp::ignorecase) str = "hello world. today wednesday" result = str.gsub(pattern) { |match| "<b>#{match}</b>" } # => "hello <b>world</b>. today <b>is</b> wednesday" i couldn't understand why had "word, is" 1 of matchedterms given example output... simplified "is" . if wanted "word, is&q
