HTML or IFrame Scraping Help

[brycedewitt]

the short question
tl;dr I’m trying to figure out how to parse through and scrape values from a specific webpage and display within module (specifically, this page).

the long question
My university has a webpage that displays current activity levels at all gyms on campus. I’m able to simply display the entire page using the IFrame module, but it’s messy and gives me a lot of data and structure that I don’t particularly need. Essentially, I’m trying to find a way to parse through the HTML and just grab the name of the facility and it’s associated value, and display it as a simple bar chart. I’m pretty well-versed in Java, but this is my first Javascript project, so I’d just appreciate some general direction on where to start/if it’s even possible.

Thanks guys.

@brycedewitt You should definitely try to give Tabulator a shot. AFAIK, Tabulator has a HTML table to JSON converter and is very flexible in making awesome tables. Warning, is that it may be a bit overkill for what you want to do…

I’m not as overly concerned with the finished product as I am about just figuring my way through some cool stuff on the way, so I’ll definitely give that a go, thanks.

@brycedewitt In this part of my module I’m scraping a website of a parcel carrier, so it’s possible https://github.com/fewieden/MMM-ShipmentTracking/blob/master/carriers/DHL.js
