OK, so my previous solution does not work very well. Converting from 'binary' to 'string' does not seem to be easy. Assigning the binary variable to a string variable results in gibberish, even with the string() function. The good news is I found a better solution:
- Save your parameters as an XML document.
- In your Read String activity, use a 'xml' type variable as the output.
So, take this basic XML code for an example:
Coke
Cheese
mushrooms
If you save this to your watched folder and read into an 'xml' variable named 'myXml' using the Read String activity, you'll be able to do the following (assuming myString is a 'string' variable)
/process_data/@myString = /process_data/myXml/drink
/process_data/@myString = /process_data/myXml/pizza/top1
(etc.)
