This fork exists solely to prevent the parser from infinitely looping when an invalid expression is parsed such as:

Slick
Slick is a standalone selector engine that is totally slick. Slick is split in 2 components: the Finder and the Parser. The Finder's job is to find nodes on a webpage, the Parser's job is to create a javascript object representation of any css selector.
Slick allows you to:
- Create your own custom pseudo-classes
- Use the Parser by itself.
- Find nodes in XML documents.
The Finder
