| # 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. | |
