Search a list of want-to-see shows in Live TV listings on Plex

The problem I’m trying to solve is to search Live TV listings on Plex once a week automatically. I have a list of TV shows and Movies and I would like to know if they’re coming up in the TV schedule.

I’ve created two shortcuts for the Mac:

Note, I’m actually selecting all the text on the Plex search results page in Safari and copying it. I’ve tried using a ‘Get contents of web page’ action instead without success.

Does anyone know where I’m going wrong? Or, perhaps there is a better approach to solve the problem.
