Documentation lacking for DDC/DDN

Is your feature request related to a problem? Please describe. I tried to manually add a node for data driven content and it kept telling me that my regex needs 2 or 3 capture groups and pointed me to the help. There was no link to any help and the help I found didn’t explain the error. It is unintuitive and explained nowhere that I could find. In particular the help page for the DDC here or the built in help, which is a copy of the text on the website do not explain how the regex should be formatted.

Describe the solution you’d like Documentation about what the capture groups do, why you need 2 or 3 of them and what they represent. I would imagine a single capture group is enough to define which part of the url is responsible for a data drive node.

Describe alternatives you’ve considered Nothing reasonable comes to mind.

Additional context I tried to create nested DDN for a website like https://domain.tld/someStaticString/<<node>>/<<node>>/someStaticString/<<x-index>>/<<y-index>>.png by adding each node individually and it created a huge mess and I couldn’t figure out how to do it and display it as a tree structure that made sense. And of course I couldn’t add all the regex groups because that would be not 2 or 3 groups. Adding everything to one thing would flatten the tree.

Would you like to help implementing this feature? I have no java experience and I can’t write the documentation about a feature I don’t understand and thus want the documentation for.

By standard I mean how often you would come across something like this.

I’m curious what comparable tools do this an ‘easier’ way or have this as a ‘standard’ feature?
