How does javascript-php parse the DOM like javascript?

Js is generated for html. For example, I want to verify {code ...} if jquery is used, alert ($ (& #039; # demo_div & #039 ;). attr (& #039; display & #039;). However, if I use php on the server to capture DOM elements in a webpage, then, how can we analyze its css attributes with css? Is there... js born for html? For example, I want to verify

If jquery is used, alert ($ ('# demo_p '). attr ('display'). But how can I capture DOM elements in a webpage using php on the server and analyze its css attributes with css? Are there functions or classes that have been written?

Please read this question carefully before giving the subject a question "like"Supplement 2AndComment 7 floorTo see if this should be done.

The Y Problem of the landlord can be solved by itself, but the subject should learn a lesson again to find out XY Problem's bad practices.

You should go back and reflect on it. Read "Wisdom of Inquiry" several more times, and leave less time-consuming guessing games for the community.

Supplement 1:

You may consider using PHP to call a rendering core that only supports HTML + CSS (without js), and then use the rendering result. At least:

• Properly tolerate small issues in HTML and get a standard tree DOM Structure
• Accurately process CSS overwrites and obtain any CSS attribute of a specific element.

If you want to achieve root removal, do not just think about doing this in the PHP framework.

To fully meet your needs, simply relying on any PHP library is useless.Any. No. No doubt.

Because of a simple principle: If we analyze only the HTML string text of a webpage, we cannot determine the state of a last attribute of demo_p.
