How to properly parse a page and display all the resources on it?

Question

PHP

There is such a task:
you need to parse the page, show it in the browser, with styles and pictures, a person must select an element with the mouse, for example, the name of the product.
Roughly speaking, Google's "Structured Data Markup Wizard" is similar. how to do it right? are there any tools?

Answer 1

If not tied to PHP, then one of the powerful tools is Scrapy , and the visual markup on top of it is Portia .
I did not find anything similar for PHP or other languages.
