Solomon,
I was able to replicate the problem and I think I understand the issue now. Is the XML requirement rigid? If so, the fastest solution is to execute a Python script that converts the XML into a CSV and then you can parse that CSV with VB if it’s particularly nasty or you can import parameters from that CSV through one of the Programming commands. (My personal preference is to always use VB tho).
You can also call Python scripts from a VB. I have some old code laying around for that.
Here’s a good thread: Tecan Fluent & Python
Edit: There is another way but I would need to test it.
