Identify broken links--Software?

I am also interested in this information.  We currently have an intern going back through our 700+ courses to create spreadsheets of the links contained in each course so we can easily check them without having to go through the course itself.  

In another discussion (Broken Links Checker), Stephen Miller said his team uses Integrity for Mac to check their courses' HTML for "broken links, 404s, and redirects." 

If anyone knows about other software for this, I hope they'll provide that info. 

To me that sounds like:

1. Iterate the entire folder where holds all courses
2. Iterate every story.html, or other files needed, in all sub-folders and return with all hyperlinks from <data-url> tags, or other tags include one
3. Run the entire link bulk with a link checker. Might be slightly tricky because by automation, it is easy to recognize a 404, but it may be harder to recognize when the link works, but the content I want is not there now.

Talk to an indy Python programmer if you don't have a in-house one. They might have tools to develop an one-stop shop to all requirements above.

Did anyone find any solution to find a broken links from the courses created using Articulate Storyline 360?

Above post suggested to write a python script, did anyone tried? What should be the source file? SCORM or Story file
