Amazon and answer.xml, How to write my own browser with paradox

[-Ping-]

I'm looking for information at amazon.com and be able to generate an
querystring for my browser.
I am able to generate this querystring by opal,
sending it to my browser, but only get an *.xml answer shown at my
browser. I'm able to extract the information by stringextract, but how
to start direct internet-comunication with receiving the answer with
opal? (similar: how to write my own browser with paradox?)

Any ideas?
