Is there a solution (extension, service) for collecting (parsing) news from HTML, storing, and displaying?

Question

Parsing

It is necessary to receive data from HTML (and not from RSS) from pages, store and display with sorting ... Basically, there are parsing with export to some format. And you need to get data from HTML (text, link, date, etc.), store, display.

Upd.
We need something similar to an RSS reader, but which would work with HTML (set selectors / xpath of the name, url, image, date, description for each resource, etc.), parse and write this data to the database (well, the output is optional).
