Filtering post message on output

[Parsnip]

I'd like to make an add-on to filter and replace certain message text when it's being output, where should I be looking to extend for this?

I've been able to make an add-on to do it before it's written to the database by extending Datawriter DiscussionMessage Post.php but now I need this to happen after the message is retrieved as I don't want the filter to be permanent.

I'd think you'd want to extend XenForo_ViewPublic_Thread_View

Thanks, after having a look around in there I think I might have a fiddle with /ViewPublic/Helper/Message.php
