I'd like to be able to save a copy of questions on which I've participated (asked, answered, and ideally commented but that's less important) from a site (beta, if it matters) in a human-readable form. (Text, HTML, XML with a known schema... not picky here.) I understand that I could use the data explorer to extract some of this, but not full copies as far as I know. I see that there is an API that might be able to help me if I knew webapps better or JSON at all.
Has somebody already written something like this? Or is there some other way to do this? Is my best bet to just download the data dump and trawl through it looking for my stuff?
(In case it matters, the specific case prompting the question is a site where I have a couple hundred posts -- not thousands, but not so few that just doing it by hand is obviously the right approach.)
I've seen this similar question.
(When I wrote this question beta sites were not included in SEDE or the data dumps. Now they are, but I still don't see a clean way to extract whole questions based on my participation.)
