# css-what [](http://travis-ci.org/fb55/css-what)
a CSS selector parser
## Example
```js
require('css-what')('foo[bar]:baz')
~> [ [ { type: 'tag', name: 'foo' },
{ type: 'attribute',
name: 'bar',
action: 'exists',
value: '',
ignoreCase: false },
{ type: 'pseudo',
name: 'baz',
data: null } ] ]
```
## API
__`CSSwhat(selector, options)` - Parses `str`, with the passed `options`.__
The function returns a two-dimensional array. The first array represents selectors separated by commas (eg. `sub1, sub2`), the second contains the relevant tokens for that selector. Possible token types are:
name | attributes | example | output
---- | ---------- | ------- | ------
`tag`| `name` | `div` | `{ type: 'tag', name: 'div' }`
`universal`| - | `*` | `{ type: 'universal' }`
`pseudo`| `name`, `data`|`:name(data)`| `{ type: 'pseudo', name: 'name', data: 'data' }`
`pseudo`| `name`, `data`|`:name`| `{ type: 'pseudo', name: 'name', data: null }`
`pseudo-element`| `name` |`::name`| `{ type: 'pseudo-element', name: 'name' }`
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr]`|`{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }`
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr=val]`|`{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }`
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr^=val]`|`{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }`
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr$=val]`|`{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }`
`child`| - | `>` | `{ type: 'child' }`
`parent`| - | `<` | `{ type: 'parent' }`
`sibling`| - | `~` | `{ type: 'sibling' }`
`adjacent`| - | `+` | `{ type: 'adjacent' }`
`descendant`| - | | `{ type: 'descendant' }`
__Options:__
- `xmlMode`: When enabled, tag names will be case-sensitive (meaning they won't be lowercased).
