This does not appear to be true. I don't find anything searching for "nhl" or "blus" in the file. Adding the lines at the end you suggested doesn't seem to make sense given the file is all html but adding it doesn't seem to do anything for me.
The program doesn't appear to detect anything anymore. Before the roster file at least appeared in the program with its image and everything. Dealing with this broken program is a complete nightmare and I'm just going to give up. My experience attempting to use it does not match what anybody tells me is supposed to happen. It almost feels like a massive troll.
