11 <blockquote>
12 <p><a href="foo.html">The History of Foo</a><br />
13 An <span color="red">informative</span> piece of <FONT FACE="ARIAL">information</FONT>.</p>
14 <p><a href="bar.html">A Horse Walked Into a Bar</a><br/> The bartender said
15 "Why the long face?"</p>

22Can you stand to look at it? Just look at those blank lines and random line breaks, trailing spaces, mixed tabs, deprecated tags... it's outrageous!
23
24Let's clean it up...
25
26```bash
27$ npm install clean-html
28```
29
30```javascript
31var cleaner = require('clean-html'),
32 fs = require('fs'),
33 file = process.argv[2],
34 options = {'pretty': true};
35
36fs.readFile(file, function (err, data) {
37 process.stdout.write(cleaner.clean(data, options) + '\n');
38});
39```
