is it possible to retrieve data from remote form, from another domain that I can't control.

I want to type in number in my local form text field and then post it to remote form and retrieve data. I know how to retrieve data from local mysql, but don't know how to retrieve it from remote form.

Remote form:  http://www.otto.de/is-bin/INTERSHOP.enfinity/WFS/Otto-OttoDe-Site/de_DE/-/EUR/PV_DirectOrder-Start?ls=0#lmPromo=la,3,hk,home,fl,Sidebar_Bestellen

Working number: 31477682

I want to type in 31477682 on my local text field and retrieve data(price, color, status like "lieferbar") from another domain.
