How to parse vk comments correctly?

Question

CMS

Good day, tell me how to be.
I plan to make an information site covering the situation on some sections of the road. It was planned to take information about these sites from some VK communities that were made specifically for these sites. A post with hashtags with certain road names is published in the communities, and in the comments people write what the situation is at the moment, but not all messages are informational, some can even ask a question. How to parse the necessary information to the site?
Of course, you can think about Yandex traffic jams, such as what is the problem, take information from there, but they do not display in these sections of roads.
If I didn’t express myself correctly, then I’m sorry, I can’t give full information yet. I wrote the most basic.
