How to process this string via regular expression
- by iiduce
my string style like this:
expression1/field1+expression2*expression3+expression4/field2*expression5*expression6/field3
a real style mybe like this:
computer/(100)+web*mail+explorer/(200)*bbs*solution/(300)
"+" and "*" represent operator
"computer","web"...represent expression
(100),(200) represent field num . field num may not exist.
I want process the string to this:
/(100)+web*+explorer/(200)bbs/(300)
rules like this:
if expression length is more than 3 and its field is not (200), then add brackets to it.
