How can I use regex to split an expression like the following :

(Round(340/34.12)*2)

into this list :

(
Round
(
340
/
34.12
)
*
2
)

I could not find a sample to this in .Net help.


Thanks in advance,
 
When you say "like" do you mean exactly or similar.

1) Is the function "Round" always part of the expression or can there be
other functions or even no function?
2) Are all the numbers always in their shown format or can they all be
floating numbers?
3) Are parenthesis optional?
4) Do you allow any operators to be used?
5) Are you looking for the ability to parse ALL mathematical expressions in
the universe?
6) Do you allow whitespace to separate symbols?

This is effectively a parsing function and RegExp aren't strong enough. Do you
want to handle precendence of operators as well? That is,
A + B * C

What are you really looking to do?
