# css-what [](http://travis-ci.org/fb55/css-what)
|
|
|
|
a CSS selector parser
|
|
|
|
## Example
|
|
|
|
```js
|
|
const CSSwhat = require("css-what")
|
|
CSSwhat.parse("foo[bar]:baz")
|
|
|
|
~> [
|
|
[
|
|
{ type: "tag", name: "foo" },
|
|
{
|
|
type: "attribute",
|
|
name: "bar",
|
|
action: "exists",
|
|
value: "",
|
|
ignoreCase: false
|
|
},
|
|
{ type: "pseudo", name: "baz", data: null }
|
|
]
|
|
]
|
|
```
|
|
|
|
## API
|
|
|
|
**`CSSwhat.parse(selector, options)` - Parses `selector`, optionally 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 | properties | 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:**
|
|
|
|
- `lowerCaseTags`: When false, tag names will not be lowercased. Defaults to `true`.
|
|
- `lowerCaseAttributeNames`: When false, attribute names will not be lowercased. Defaults to `true`.
|
|
- `xmlMode`: When `true`, `xmlMode` implies both `lowerCaseTags` and `lowerCaseAttributeNames` are set to `false`.
|
|
|
|
**`CSSwhat.stringify(selector)` - Turns `selector` back into a string.**
