Question - easier way to get all rules of multiple types?

[jamesaspence]

Hello. I'm digging into this library for the first time and am trying to parse a stylesheet, in order to pull all font-family/ font-face declarations out of it. I've found that to be rather difficult - when working with a stylesheet instance, I have to call getAllStyleRules, getAllMediaRules, etc. etc., and iterate my way through many layers.

Is there any way to do this easier, without requiring so many manual calls? I would use getAllRules but that returns a very generic rule instance (ICSSTopLevelRule), and I'm trying to avoid having a large if statement chain within my code to check for relevant class instances, just to retrieve child declarations.

You may want to have a look at class CSSVisitor.
Call visitCSS using the parsed CascadingStyleSheet and as visitor use a class derived from DefaultCSSVisitor.
Overload onDeclaration and check for font-family or whatever you need.

Does that help you? Can the issue be closed?

@phax haven't gotten the chance to revisit, so yes, let's close for now - I can always reopen if this doesn't work. Thank you!
