Question

Parsing

I want to learn how to parse text data from various sites and forums, getting a txt file with captured data as output, for example:
https://www.dreamstime.com/forumm_35047_pg1 It is required to parse messages from 10 pages.
https://www.litres.ru/mitio-kaku/buduschee-razuma/... It is required to parse reviews for the book.
Which text content parser is the easiest to learn for a beginner, where should I start?
Are there easy-to-learn solutions?
