During testscan I am using semicolin(;) as delimiter but I want to skip this delimiter if it is present within single quotes.

How can I do it?

Example,

string1 = string2 ; xyz.data = 'string3(1 = string4; 0 = string5)' ; sring6;

Expected output: Semicolon inside value to need to be skipped

value1 =>  string1 = string2
value2 =>  xyz.data = 'string3(1 = string4; 0 = string5)'
value3 =>  sring6
