Hi jwkrahn,

Your solution look interesting. However, after I google it I am not so understand the zero-width assertion (I never touch the extended thing). Would you like to explain it little more? Thank you

**For all,

Thank you for your replies. The magic capturing parentheses works! However, as far I know, the parentheses is usually used with include the string store in variable into a pattern. If the parentheses is the only way to do the inclusion, would it mean I will get the capturing effect? Also, Does capturing cost more in a regular expression matching?
