+# css-what [![Build Status](https://secure.travis-ci.org/fb55/css-what.svg?branch=master)](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).
