how to handle dynamic page in guidatv.sky.it.ini?

Hi,
I was going to try to update this ini after the website changed, but I found a problem. wg++ downloads the page when it is not fully loaded. It seems that the page runs some script after first loading and updates the info in it.
For example, in Chrome, if I "inspect" an element, I see the correct info, but if I "view page source" then the info is wrong or not there at all.
The index page need probably 0.5 seconds or so, before is fully loaded.
How to deal with this?
Thanks!
