At this point, I have the whole node in the variable:
I also tried to put this into an output context of the extract action as "userNameNode".
For the next action, I'm using the set-var action and trying to extract the text (JOE) of the variable (or it's input context, which is "userNameNode"). In the probe, I don't see the content of the "userNameNode", so I'm assuming I need to extract it from the content of the 'var://context/sourceUserName/userNameNode' variable. I've been horribly unsuccessful.
See the attached image of the whole policy, and then the settings of the extract and then the set-var actions. I don't know what the set-var action is actually able to see here.
Ideas are appreciated.
