I have a mathematical expression such as:
expression = function123(v1, v2)
and I want to transform it to:
expression = (function1(v1, v2) + function2(v1, v2) + function3(v1, v2))
In order to solve this problem, I tried to utilize regular expressions, such as:
and replace using the interior tokens to get what I want.
Regular expressions come with certain limitations and problems. that can be identified in the following examples:
expression = myfunction123(v1, v2) + function123(v1, v2)
The above example would create problems because
my would be get messed up.
expression = function123(normalized(v1), normalized(v1))
The above example would create problems because the interior nodes would not be able to be extracted.
So basically I understood that regular expressions are not enough to solve this problem so I need something like an
abstract syntax tree.
Does anybody have any experience with such a problem that could guide me to accomplish what I described?
Thanks a lot in advance.
