An array of tags like []nostr.Tag or a flat array of strings? You just have to use range to build your array how you like it..
Discussion
Do you have an example? I had no problems to get all contacts with something like
pTags := []string{"p"}
allPTags = ev.Tags.GetAll(pTags)
but I don't know how to get the relays.
For nip65 it's "r" tags it looks like, maybe that's why you can't find em yet? P tags are usually for a person.
If I filter for kind 3 I'll get something like this:
[p 7cc328a08ddb2afdf9f9be77beff4c83489ff979721827d628a542f32a247c0e]] {"wss://eden.nostr.land":{"read":true,"write":true},...
It seems like the prefered relays just follow the "p" tags.
Oh ya, if you're looking at kind 3 then that list is in the event content. Not the tag. But the p tag also has a relay in it optionally but it's not very reliable.
Yeah, I'm looking for my own relays in the event content, but I don't manage to get these into an array.
The content is an extra field, you probably have to json.Unmarshal it separately.
