I have a scene with two cameras - a primary camera and plan view camera. How can I render the plan view camera to a plane attached to the primary camera?

I'm trying to get article titles from yahoo news and organize it in a json file. When I dump the data to a json file it appears confusing to read. How would I go about organizing the data, either after the dump or from the beginning?

This for a web scraping project where I have to get top news articles and their bodies and export them to a json file which can then be sent to someone else's program. For now, I'm just working on getting the titles from the yahoo finance homepage.
