|

|
> 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.
