When outputting XML, how can I prevent to output empty tags for specific data?

Question

When outputting XML data, I would not like to output empty tags when the input data does not have any information.
How can I accomplish this?

Answer

By using the If Loop logic in a loop process, it is possible not to output empty tags for nodes with no input data.

Process overview

Mapper checks whether or not each element is empty, and outputs data only when element is not empty.

1. Check whether the target element matches empty character or not.

2. Perform If Loop logic on the element and output only if it does not match empty string.
