Hello.. I had no luck to find a good way to achieve the following:

suppose i let the user to write a condition using javascript

INS>5 || ASTO.valueBetween(10,210) ... etc....

I tried to find a way to get the variables name...from JAVA... Rhino library didnt help a lot... However i found that handling exceptions i could get all the identifiers! Everything is great but one little problem..... How teh heck i can replace these identifiers with the numeric id of each var ? eg INS to be _234 ASTO to be _331 ?

I want to to this replace because the name may change...

I could do it using a replace but i know that this isnt easy because...

1) replacing _23 with MPLAH may replace also _234...(this could be fixed with regexp somehow..)

2)what if _23 is in a comment section ? rare to happen but possible /* _23 fdsafd ktl */ it should be replaced...

3)what if is a name of a function ??? _32() {} rare but shouldnt be replaced

4) what if it is enclosed in "" or ''??? And i am sure that there should me a lot more cases..... any ideas ?

thank yoyu for your time
