用于HTML和CSS的PHP DOM解析器

Is there any HTML / CSS DOM parser for PHP that I can feed direct live URL and it gives me following two things.

1. HTML of any class/id of the component.
2. Custom CSS that is applied to any class/id.

I know num:1 is possible with so many DOM parser that are available but I also want the CSS properties that are associated with them.

try to use html_dom_parser

which will give you all html finding support
