# postcss-selector-parser [](https://github.com/postcss/postcss-selector-parser/actions/workflows/test.yml)
> 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.
