How to capture paste event and modify HTML attributes

[raxhacks]

I want to know if it is possible to somehow listen for the pasting event and modify the span tag attributes. For example I want it to be possible that when I paste some text it could be in this format:
<span data-src="test">PASTED TEXT</span>

I want it to include the data-src. Has this been possible?

You can find the possibility to listen for paste events here: https://developer.mozilla.org/en-US/docs/Web/API/Element/paste_event

Hi, thank you for the response. I already tried using the event, my question is more what function inside Etherpad's source code I can call in order to add custom atributes to the pasted tag.
