Edit content of comment after receiving handleNewComment event?

[PAK90]

This isn't exactly an issue, more of a query. I need to modify the content of a comment after it's been posted, to add icons and hoverable links to the text. For example, someone posts {abc} with the {} delimiters, I want to transform that into <img src="img/abc.png/>. Same goes for something like [] which would become <a> tags with specific classes to allow for a hover.

I've tested this in chrome dev tools, and I can manually add those tags into the <p> tag that holds the comment. However I haven't found a way to do this as a reaction to a comment being posted, since the comment is in an iframe which I can't get with document.getElementById. So, is there a way to get at that comment using your library, or using the comment.id which is given in the handleNewComment callback function? Or not possible?
