Anyone happen to know about any wokkel pubsub examples I could look at?

Zash: besides the ones in the repo?

ralphm, were there examples specific to *pubsub* that I missed?

ah, crap

let me see if I can point you to some

I got as far as making a thing that connects and subscribes to a node

I have code using it, of course, e.g. in ikDisplay, but that's not really an easy example.

Zash: maybe I can help you with something specific?

Actually, I might be a point where I'd wanna read docs on how to interact with the XML data.

Zash: I assume you have implemented an itemsReceived method on your subclass of PubSubClient?

Then, the only arguments is `events`, and it has an `items` attribute you can inspect

https://cerdale.zash.se/upload/jlSf-ddwwUkewp1n/pubsub-example.tac

Right. So an item here is one of these: https://wokkel.ik.nu/documentation/current/api/wokkel.pubsub.Item.html

as an Item is an Element, you can either use named attributes 'eg. item.foo, to get to the payload root named foo', or using the elements() function that returns an iterator of child elements

an Element has 'name' and 'uri' attributes to inspect

and you can coerce the text in an child 'bar' with `unicode(parent.bar)`

Zash: does that help?

Yes, thanks. Finding some twisted domish docs too.

https://twistedmatrix.com/documents/current/api/twisted.words.xish.domish.Element.html

Zash: I had plans to actually write more documentation, but sadly that's not happened yet

Zash: if you want to see typical use of domish Elements, I suggest looking at the wokkel code, where it parses things in methods typically called fromElement

Zash: e.g. in data_form.py or muc.py
