Subject: converting Net::HTTPOK to String or ? to use with REXML::Document ?

(was Re: constructing an (xml) request properly for http post to an
api)


THE PROBLEM:
the rexml tutorial here (http://www.germane-software.com/software/
rexml/docs/tutorial.html) suggests that Document.new expects a
string.  my xml_response is of type Net::HTTPOK, not String.  i see
that i can not easily convert this into a string with
String.new(xml_response).

is there currently a (simple) way to convert the Net::HTTPOK object
into a format (string) useable by REXML::Document, and if so, what
might that be/what would you suggest?

if i am approaching this problem the wrong way, what might you advise?


SOME BACKGROUND:
i am having trouble successfully running the rexml/document's .new
method.

i have the following in my ruby script:

require 'rexml/document'
include REXML
.
.
.

(i successfully receive an xml response with a Net::HTTP.start call as
viewable via irb here called 'xml_response'..)

doc = Document.new(xml_response)


i am presented with the following error messages:
irb(main):017:0> doc = REXML::Document.new(res)
NameError: undefined local variable or method `source' for
REXML::SourceFactory:Class

i am imitating syntax from these posts:

how were the other posts (http://tinyurl.com/3958n5, http://tinyurl.com/yo3mel)
able to utilize REXML::Document immediately -- i suspect that their
Net::HTTP .get and .new calls produced strings?

thank you for your time and help.
