How can I make a dynamic site parser? The site has blocks with matches, each block has its own special selector, XPath and CssSelector are not allowed, since every day there are a different number of matches in the blocks, I need to make an automatic parser of the results that were on the site How can I organize this, let's say parse the results of the last 1000 matches thank you
