@daniel-widrick would you hapen to knwo how to drop the raw data output?

I am trying to figure out how to extract the channel logoURL to add it such as:

    <channel id="44991">
      <display-name>3.1 WCAXDT</display-name>
      <display-name>3.1</display-name>
      <display-name>WCAXDT</display-name>
      <icon src="https://zap2it.tmsimg.com/h3/NowShowing/44991/s28711_h3_aa.png" />
    </channel>

Got it figured out!

This is now working relatively well and xmltv output is now much more complete than previously.
