Parsing html to c# after js is loaded?

Question

C++ / C#

Good evening, the question is this: I am making a
parser in C #, but I ran into a problem that the data I need is loaded only after the js script is executed.
Please, tell me how to solve this problem.

Answer 1

if the site is yours, then implement zhs and send to api what you need to parse.
if not yours, you can manually implement a zhs that will send you the necessary data.
if you need to automate - you write a vpf with a web browser, download the page, embed the necessary code into it, send it to the web browser, and there your code on the js will work and call your api.
Another option is to write a chrome plugin that will parse.
