How to save many pages of a site in pdf at once based on a template?
I want to print articles from sites, for example, from https://metanit.com , so that I can read them on paper, but print a clean article - without unnecessary elements and comments.
Tell me a program so that I can indicate that I want to take data only from such and such an element of nesting and then add it with the following articles in pdf and print the finished book from the articles?

Answer 1

in order to print articles without unnecessary elements and comments, you need to somehow download the articles, perhaps the author of the site took care of the styles for printing, or you need to write your own parser, or replace the styles
