I'm new in domoticz, but so far I succeed in setting a couple of switches

I would like to play with sensors now.
I also built my own weather station, based on weewx.
Using weewx, I can generate almost anything I want as http file.
Let's assume I'm interested in temperature, I can use weewx to easily build a temp.txt file I could access from:
http://<ip of my weewx device>/temp.txt
This temp.txt could be anything: txt, json, xml, whatever is easier !
would it be possible to just set the link in http poller and get my temperature in domoticz....maybe even without any scripts ?
