Output from Regex Find All Usage

[Oninaig]

Right now, Regex Find All outputs a list of matches. For example, I might have (, $primcolor=!blue, $seconcolor=!yellow in my prompt, and I can use Regex Find All to extract those with \$(\w+)=\!(\w+).

However, even though the output of the node is listed as STRING, it is outputting a list. This list doesn't seem to be compatible with any other type of input that would accept a type of list. In my specific example, my output looks like this:

The goal here is to somehow loop over that list in such a way that I go back to my original prompt and replace any instances of $primcolor with "blue" and any instances of $seconcolor with "yellow."

How exactly do you use the output of the regex find all node?
