DataSink - possible to save/output multiple xpath nodes?

Thanks, although this would work, as I mentioned, the amount of nodes is different for each iteration of data. Sometimes, I may only have 1 string. Other times, I may have 5. I don't want to have to have 5 concats just in case. It just looks messy and confusing if someone needs to work on the project. For now I put it in, but would like a more elegant solution if possible.
