Is there any library that would make process of making a website scrapper easier
« on: August 09, 2024, 11:19:30 pm »
Basically I want to make a web scraper for one of the sites I love that has awful UI so that I can interact with it better. Is there any Lazarus/Free Pascal library that would make this process easier? I'd rather not parse HTML by hand.

Our member benibela has a good library for that:
https://www.benibela.de/sources_en.html#internettools
Simple example that extracts all hrefs from a page:
Code: Pascal  [Select][+][-]
  1. uses simpleinternet, xquery;
  2.  
  3. var a: IXQValue;
  4. begin
  5.   for a in process('https://freepascal.org', '//a/@href') do
  6.     writeln(a.toString);
  7. end.
You need to undefine USE_PASDBLSTRUTILS_FOR_JSON in internettoolsconfig.inc.
