# oust [](https://travis-ci.org/addyosmani/oust) [](https://david-dm.org/addyosmani/oust) [](https://david-dm.org/addyosmani/oust?type=dev)
> Extract URLs to stylesheets, scripts, links, images or HTML imports from HTML
## Install
```sh
$ npm install --save-dev oust
```
## Usage
First include:
```js
var oust = require('oust');
```
Resource links can then be extracted from either files:
#### Extract stylesheets references `<link rel="stylesheet">`
```js
var hrefs = oust(htmlString, 'stylesheets');
```
#### Extract stylesheets references with media print `<link rel="stylesheet" media="print">`
```js
var hrefs = oust(htmlString, 'stylesheets', function(i, $el) {
return $el.attr('media') === 'print';
});
```
#### Extract script references `<script src>`
```js
var srcs = oust(htmlString, 'scripts');
```
#### Extract HTML imports `<link rel="import">`
```js
var hrefs = oust(htmlString, 'imports');
```
#### Extract URL references `<a href>`
```js
var srcs = oust(htmlString, 'links');
```
#### Extract image source references `<img src>`
```js
var srcs = oust(htmlString, 'images');
```
#### Extract cheerio elements alongside the value
Usefull for post processing/filtering as you get an array of matched elements
with cheerio convenience syntax (e.g. `$el.attr()`)
```js
var srcs = oust.raw(htmlString, '...');
-> [
{value: '...', $el: '...'},
{value: '...', $el: '...'},
...
]
```
