Bob,
I'm working on this now, and I picked up on the fact that I would not be
translating XML. I set this to "", but I'll remove the whole thing per
your suggestion.
I've used something like this before, but I used a "GET." A query string
is in your "POST," so everything is there. The main thing is it works
like a charm! What is true in:
req.open("POST", url + "?" + data, true) ???
Originally, my NIH data was in a form field (readable via DOM/iFrames),
and your code returns the whole page html. I need to change the dynamic
page to return NIH text only.
