[Rails] how do you access a remote XML file?

Hi, I'm trying to get a captch thing running from http://textcaptcha.com/
which displays an XML file when you trail a key on that URL. I've
tried this: @captcha = Net::HTTP.get_print URI.parse('http://
textcaptcha.com/api/8wcmmrp2tzoc0k484kkwwkwcsdbpk70q') in the
controller of the file that I want to have access to the data, but
nothing is displayed in the @captcha variable. If I direct my web
browser to that URL, however, I see the correct output.

I'm requiring 'net/http' and 'uri' in the controller. Am I missing
something?

Thanks in advance.
