Hi Luis - thanks again for trying, but this still didn't work for me. I'll convert it to a class instead. Really appreciate your help. Thank you. 

Good morning Luis. Thank you for replying. Unfortunately, this just gives me the last 3641144 of the stream, even with the "append". I may need to switch out my XML Virtual Document for an XML enable class instead. 

Really well explained, especially for those not very technical in our team. It helps explain why we should move to FHIR to improve interoperbility.  Thank you @Russ Leftwich
