Get CSS style from PHP

Question

I am analyzing pages using Simple DOM parser. It is neat, but I would like to get an applied CSS style for each element. Not only inline styles, but every style that applies to this element, being inline, inline, or external.

Is there a class that does this? If not, how would you do it? I don’t care that you don’t use styles, cascades or browser styles. All applied styles would be enough.

Answer 1

According to Martin, while you are almost writing a browser in PHP - this is a big question! As with any major project, the key is to break it down into more manageable steps (although some of them are not entirely straightforward).

You will need:

• work out which (if any) external css files are associated with
• (for Gumbo echo): find (or develop) a way to read and interpret external css, in-page css and inline css
• determine which styles apply to each element (including the styles applied by .class, #id and the element type) and the parents of each element, including rules that css override, which other CSS rules, etc.
