Plugin for istallation XML fie needed

I have to install the following link for my booking engine
https://deals.agenthub.net/ci/enter.asp?site=tvlpla&dir=srch&TravelTypeFilter=3&account=auroracruisesandtravel&aname=Nadejda+Jastrjembskaia+Elite+Cruise+Counselor&aphone=772-777-1337&[email protected]&ogid=690&ifile=blank.xml
I tried it without plugin – box doesn’t show up.
I want this link to be embedded into my page. Thank you!
