Sometimes on SO I find that the question I asked, while lengthy and chock full of details, really only served to provide me with a sounding board against which I was able to find that the answer was not with my code, but with the fact that my mental model didn't encompass all the possible details. Like for instance, XML parsing ;)
So what's the best way to handle those questions? Should I leave the original question which in hindsight looks asinine or just replace the body text? What would I put as the answer when nobody has responded?
What do you do in that situation?
