Perhaps someone could help with this example? I need to iterate
through each of the items in strings and wrap any case insensitive
occurrence of "key" with <b> </b>. If each string was always just the
word "key" I would use something like wrapper.join("key") but.. I have
other text surrounding the "key", various cases and potentially
multiple occurrences. Thank you in advance.
wrapper = ["<b>", "</b>"]
strings = ["blahblahKEY", "asdfasdfkey", "Keyasdf", "xxkEYxx", "xxKeyxxKEY"]
strings.each do |string|
# would like to print the string replacing "key" (case
insensitive) with <b>"key"(in its original case)</b>
end
# Ideally, would output:
# "blahblah<b>KEY</b>"
# "asdfasdf<b>key</b>"
# "<b>Key</b>asdf"
# "xx<b>kEY</b>xx"
# "xx<b>Key</b>xx<b>KEY</b>"
