NodeJS for CSS Parsing and Selecting

Can anyone recommend a NodeJS library similar to https://github.com/alexdunae/css_parser?

I have tried using https://github.com/visionmedia/css, but it doesn't fulfill all my requirements.

For example, when I parse the following CSS:

.behavior1 {color: red}
.behavior2 {background-color: black}

and then search for '.behavior1.behavior2', I want to receive this JSON:

{"color": "red", "background-color": "black"}
