Custom INI for XMLTV

Hi, I created a php script that generates an xmltv output

url: https://ovaluk.eu/test/oneplay_epg/0058.php

and I would like to somehow incorporate that output into webgrab directly so that it is part of the resulting complete xmltv file.. how do I achieve that?

I created my own INI file but somehow it doesn't work and webgrab throws an error:

[Critical] 
Object reference not set to an instance of an object.
[Critical] 
   at  .—. (String[])
[Critical] Unhandled Exception
[Critical] Execution stopped
