For example: "<b><i>aabbccaaaaaddee</i></b>" will become "<b><i>abcade</i></b>". That is what I accomplished in the article. I know very well regular expression and there are some way of accomplishing that but not in one step. Every char of the string must be separated by a separator (ex: comma, pipe, etc) and then apply the lookback regular expression. The beauty of using regular expressions is this: a lot of steps that are needed to accomplish some string formating/parsing can be done in one step using RegExp. But if there are the same amount of steps it will be faster not to use RegExp. Thanks for citing us but the article was about making a unique chars string.
