I want to write a regular expression that will replace the word Paris by a link, for only the word is not ready a part of a link. Example: i'm living <a href="Paris" atl="Paris link">in Paris</a>, near Paris <a href="gare">Gare du Nord</a>, i love Paris. would become i'm living.........near <a href="">Paris</a>..........i love <a href="">Paris</a>.
