 4 | 
 5 | Extract all tags from html
 6 | 
 7 | ## Usage
 8 | ```js
 9 | var extract = require('extract-html-tag')
10 | var assert = require('assert')
11 | 
12 | var html = `
13 |   <div class="foo bar">
14 |     <p class="bin baz">hello planet</p>
15 |   </div>
16 | `
17 | var expected = [ 'foo', 'bar', 'bin', 'baz' ]
18 | assert.deepEqual(extract(html), expected, 'array was same')
19 | ```
20 | 
21 | ## API
22 | ### `classes = extract(html)`
23 | Get an array of classes for the given string. Uses a regex so safe to run on
24 | non-html strings too. Returns an empty array if no matches are found.
