How to build a list of items from another site

Let's say for example that I have a web URL "mydomain.com/list". This page contains a whole bunch of HTML list item elements.

Now I want my IONIC app to read and display these items. I would NOT like to display the web page with the in-app browser. It must display the list items in my own format.

I can't find any resources online to tell me how this would be possible. Perhaps using some kind of web-scraper or am I being too complex? Can I just use javascript to loop through the list item elements?

Any suggestions would be immensely helpful!
