Copy data from Webform submission to a node? I have pre-existing node authored by each user. However, for presentation purposes, I use a Webform to collect data from the user.

Existing Node: Assessment

field_question2
field_question3


Webform


field_question1
field_question2
field_question3


On submit, I would like to compare "the user submitting the Webform" with the author of existing nodes, then set the field values of the submitter's existing node with the new values from the submitted webform.

This worked well in Drupal 7, but in Drupal 8 I don't seem to understand the syntax, nor do I see a place to set up or pass variables.

Can this be done in the current state of Drupal 8 Rules?

To my knowledge the answer to your question is No (it's part of what this is all about).

If you're in for getting a better understanding about all this, then have a look at these links:
