The last statement was me wrangling with XMLTV getting EPG data to import for japanese ~~pirated~~ rebroadcasted IPTV.
It was actually painful to configure the XML statements to scrape the data as I had to both understand how the values were derived and how I need to change them as they were regional stations.

In the end it was this syntax:
Example from their page: <channel site_id="23##10##101040" xmltv_id="日テレ">日テレ</channel>
Actually needed was the info inside the site_id:

• 23 = Region
• 10 = Terrestrial (they seem to have different digital networks)
• 10140 = The number of the channel (same channel-name for different regions
• (unmentioned here but in another example they had an additional number after the 10140 which incremented by one or two without any understandable reason)

I had to get the region from the URL/source code out of the dropdown menu and find out that the type of broadcast is somewhere hidden in the html table and that there is is a small number besides each channel name dependant on the region)

Edit: This whole endavour took me 3 weekends to implement into my setup
