title: Regular Expression extract first three characters from a string
body: <p>Using a regular expression how can I extract the first 3 characters from a string (Regardless of characters)? Also using a separate expression I want to extract the last 3 characters from a string, how would I do this? I can't find any examples on the web that work so thanks if you do know.</p>
