Question

I have a string: Something 8:45 foo bar foo bar at 23:50

How to highlight and mark with <b> tag all time combinations in string like 8:45 and 23:50?
As a result I want to have Something <b>8:45</b> foo bar foo bar at <b>23:50</b>

Answer 1

You can do this:

"Something 8:45 foo bar foo bar at 23:50".gsub(/\d{1,2}:\d{2}/).each {|hour| hour = "<b>#{hour}<b>" }

Identify hours and replace each one with <b>hour<b>
