I'd like to convert a web page like this and have the program filter it for the comments, rather than include "permalink, source" or irrelevant page elements.
A very general question so a very generalised answer:
The following tool chain can, (on just about any platform):
- Scrape a web page
- Identify specific elements
Read them out loud
All of the above are Free, Gratis & Open Source, and cross platform so will work on at least Windows, Mac OS-X and Linux your question didn't specify a platform.
An example for Linux using the command line tools, (curl), and some of the above:
curl -s http://api.icndb.com/jokes/random/ | python3 -c 'import html.parser, json, sys; print(html.parser.HTMLParser().unescape(json.load(sys.stdin)["value"]["joke"]))' | google_speech -
