# bo-selector

A CSS selector parser based on [jison](http://zaach.github.io/jison/)

[![Build Status](https://secure.travis-ci.org/featurist/bo-selector.png?branch=master)](http://travis-ci.org/featurist/bo-selector)

### Example

```js

var parser = require('./bo-selector').parser;

var ast = parser.parse(".a[b = c], c[d]:e:f(g *:h:i[j]:k), :l > m[n ~= 'o']");

console.log(require('util').inspect(ast, false, null));

```

...generates:

```js

{ type: 'selector_list',

  selectors:

   [ { type: 'constraint_list',

       constraints:

        [ { type: 'class', name: 'a' },

          { type: 'attribute_equals', name: 'b', value: 'c' } ] },

     { type: 'element',

       name: 'c',

       constraints:

        [ { type: 'has_attribute', name: 'd' },

          { type: 'pseudo_class', name: 'e' },

          { type: 'pseudo_func',

            func:

             { type: 'function',

               name: 'f',

               args:

                { type: 'selector_list',

                  selectors:

                   [ { type: 'combinator_selector',

                             { type: 'pseudo_class', name: 'i' },

                             { type: 'has_attribute', name: 'j' },

                             { type: 'pseudo_class', name: 'k' } ] },

                       combinator: 'descendant' } ] } } } ] },

     { type: 'combinator_selector',

       left:

        { type: 'constraint_list',

          constraints: [ { type: 'pseudo_class', name: 'l' } ] },

       right:

        { type: 'element',

          name: 'm',

          constraints: [ { type: 'attribute_contains_word', name: 'n', value: 'o' } ] },
