Say there is an article where I want to move the reference tags that appear before a period to be moved after the period. Example:

From this blah blah. To this blah blah. Notice the period's location. I have a find and replace tool from DEV, which supports RegEx. I am curious how I could make this happen with RegEx, but I don't know much about RegEx to do it. Does anyone out there with RegEx knowledge and experience know how I can do this? This would be a great help to me.
