Css interpreter with visitor pattern

Download by package console

install-package CssSyntax

Given you want know how many selectors are in your css, implement your own walker class and overriding methods you want to work:

public class SelectorCounterWalker : CssWalker
{
	public Int32 CountSelectors { get; private set; }

	protected virtual void VisitBeginSelector(string selector, int line, int column)
	{
		CountSelectors++;
	}
}

Execute walker:

var css = @"
    #edit-task { padding-top : 10px; }
    .btn {
        margin-top: 10px;
        background-image: url(../img/bk.jpg);
    }
";

var reader = new StringReader(css);
var walker = new SelectorCounterWalker();
walker.Visit(reader);

Console.WriteLine(walker.CountSelectors); //print: 2

Great! Feel free to pick one of the issues, or submit a bug/feature you would want to work on.
