How to create XMLTV?

[Carmelo Campos]

I already have a personal m3u8 where I have a couple of channels, but I would like that in the programs the tv list comes out, at the moment I only find the tv if I search for them. I have tried several ways to create the XMLTV but I have not been successful.
Here is the link to my updated EPG. https://iptv.monstertv.net/tvdata/epg.xml

You could try something like zap2xml.  It requires that you create an account on zap2it.com.
Confusingly, zap2xml and zap2it do not seem to be affiliated with each other, but simply named similarly.

Yes, but the channels I have are not in that provider.
Do you have any XML as a result ? To compare and see how to create a similar one
