Calculate the specificity of a given selector #39

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago

Would it be possible to calculate the specificity of a given selector based
on the W3 specification 

http://www.w3.org/TR/CSS2/cascade.html#specificity

There is a ruby project that does this and I think it would be a handy feature.

http://code.dunae.ca/css_parser/

CssParser.calculate_specificity('#content div p:first-line a:link') 
=> 114

My goal is to be able to take an html document and parse it applying all
the css styles inline on the actual elements. This is useful in getting
good email rendering results and I got the idea from premailer

I'm looking at the implementation of CssParser.calculate_specificity and it's 
so 
dead simple that it would stand on its own fine without any help from Fizzler. 
The 
only downside is that this implementation assumes a valid selector syntax. I've 
attached a C# port with tests. 

The Fizzler way to address this, though slightly more involved, would be to 
write an 
ISelectorGenerator implementation that carries out the calculation. The upside 
here 
would be calculation over a validated syntax.

Thoughts?
