You seem to have ignored: 'The thread information boils down to "parent ID" and "root ID", which are exposed in at least one XML feed'.

Maybe a misunderstanding ... I thought if a feed exposes this info, a feed reader like Thunderbird should be able to extract them and produce a thread-outline! So one only need to recommend this "rich" feed!

But you want to tell me instead of parsing the RAT-webpage I should better write a client parsing this feed. Right?

As I said I'm new to RSS ...

Ah, so you are using Thunderbird and it produces thread outlines for other RSS feeds? That certainly more useful information for figuring out what you want.

You seem to be waiting for somebody to figure this problem out for you. And nobody seems to be doing that. So I suggest you go read up on RSS and/or Thunderbird and figure out what is needed in an RSS feed in order for you to get the behavior that you want. That seems a lot less work and more promising than trying to write a "parse RAT's HTML" script.

Then when you have something much more concrete to request, you'll be more likely to get the RSS feed "improved" or help in writing a wrapper for the RSS feed (or something).
