By the way, Edsil, I think that I may have been too quick responding to
your apparent requirement for top and right side position.
Ideally one would hope that you could identify the document element of
interest, and run a JQuery-like request for .position(). Then compare the
left/right results to surmise the most likely in the top and right in the
document. I have since learned in posting a question to Google Group
nokogiri-talk that Nokogiri does not provide that level of JQuery-like
results. So I asked the question:
"So finding position is out of the question. What I am interested in
learning is this: A particular web page arbitrarily and randomly
provides/places a certain div. I can identify that div, but I am just not
sure where it is located in the entirety of the document. What methods do
you suggest as most helpful... I can work with even sort of vague or
uncertain suggestions."
And a person there, sorry I don't have permission to identify him,
responded with:
"You may want to try using the ".path" method if you've found a particular
Node, which will basically tell you where in the XML document tree that
Node is. Specifically, it returns the XPath query string which you can read
more about if you Google "w3c xpath"."
Hope this helps
Liz
