# postcss-selector-parser [](https://travis-ci.org/postcss/postcss-selector-parser) |
|
|
|
> Selector parser with built in methods for working with selector strings. |
|
|
|
## Install |
|
|
|
With [npm](https://npmjs.com/package/postcss-selector-parser) do: |
|
|
|
``` |
|
npm install postcss-selector-parser |
|
``` |
|
|
|
## Quick Start |
|
|
|
```js |
|
const parser = require('postcss-selector-parser'); |
|
const transform = selectors => { |
|
selectors.walk(selector => { |
|
// do something with the selector |
|
console.log(String(selector)) |
|
}); |
|
}; |
|
|
|
const transformed = parser(transform).processSync('h1, h2, h3'); |
|
``` |
|
|
|
To normalize selector whitespace: |
|
|
|
```js |
|
const parser = require('postcss-selector-parser'); |
|
const normalized = parser().processSync('h1, h2, h3', {lossless: false}); |
|
// -> h1,h2,h3 |
|
``` |
|
|
|
Async support is provided through `parser.process` and will resolve a Promise |
|
with the resulting selector string. |
