I'd suggest that you use HTML::LinkExtor to grab all of the links off of the page, then sort through them looking for the ones you actually want.
In some cases, that might work, but for this particular one, he has no way of determining which links were those of "authors" who replied to
Name Space.
As for HTML::TreeBuilder, demerphq puts on a nice show on how you'd do it, but for me, it's too much work (and a lil'bit of a mind ben).
