XML Code Notes (data structure) : How to use ?

[PhilB-RLB]

Hello,
it's noticed here (https://github.com/zadam/trilium/wiki/Note) that "code note - some kind of formal code, typically programming language (e.g. JavaScript) or data structure (e.g. XML)" can be used in Trilium Notes.

I would like to use it to read some data for my music album collection. At this time, when I add a new album I select an artist from a list provided by a Promoted Attribute. This list show the artists last names in an alphabetical order :
...
Beatles (The)
Bowie, David
Clapton, Eric
...

Now, let says that I select the artist name "Bowie, David" from my dropdown list, how can I retrieve the following information from an XML Code note to obtain the following values in a script :
Artist First Name : David
Artist Last Name : Bowie

What would be the XML structure of note ?

The idea is to set a text for a new note with David Bowie (instead of the Promoted Attribute value "Bowie, David).

If you can choose then I recommend JSON since it's easier to work with in JavaScript.

Not sure how much you already know, but once you have a note object, then getting the underlying JSON data content is simple like this:

const data = note.getJsonContent();

for (const artist of data) {
     console.log(artist.firstName, artist.lastName);
}

Structure can be whatever you want, e.g. array of objects as used in the code sample.

Hello Zadam, once again thank you for your help.

Could you please provide the syntaxe to use in the JSON note in order to use you previous code example ?
