The attached VI works when I run it initially creating the XML file, but when run after the XML file is created, it's not updated. What am I doing wrong?

The attached VI works when I run it initially creating the XML file, but when I change data and run after the XML file is created, it's not updated with new data. What am I doing wrong?

Thank you.

That looks like the logic which was written into the VI

Inner true/ false case:

(file exists : false) write to XML file, unflatten for display

(file exists : true) read from XML file, unflatten for display

At no time when the file exists (true case) is the XML file updated...
