how to customize variable name

Hi,

I want to access desired variables by passing variable name type string to it and it will give me value of the variable.

eg.

variableName (type string)="variable1"; <input parameter>

variableOutResult (type int) <output parameter>

variable1 <int type>=1; (default value)

variable2 <int type>=2; (default value)

using setValue activity. I want to create an expression which will return default value of variable1 or variable2

XPath mapping

(Location)                                                                                 (Expression)

/process_data/@variableOutResult                                            "/process_data/@"+"/process_data/variableName"         <red colored string is access to a variable which has value as variable1 or variable2>

underlying vauriable will form "/process_data/@variable1" which should store value to variableOutResult and give result as 1.

Please let me know if you need more clarification.

Regards

Sunil
