Regular expression to parse variables or words from a string, but not
function names.  Example:
LTE(TARGET_SCENARIO_NO,0)*0 +
(GT(TARGET_SCENARIO_NO,0)*(NET_REVENUE-GROSS_MARGIN+TARGET_GROSS_MARGIN))


If I use a regular expression that looks like:

\b([a-zA-Z])(\w+)?\b

I can get all the words separated.  However, it also gets LTE( and GT(
which I want ignored because they are functions.  A function is
defined because the ( comes right after the word.

I am using .NET 2.0.

Hi,

at first, please excuse my bad english :/
A common trick is to parse everything allowed and then negate that expression. 

([a-zA-Z]\w+)[^\w(]

with your example and only got the variable back. The ^ sign in
brackets that we allow everything besides \w and (

Have fun :)

Hope this helps or points you to another solution.
