clean-html

HTML cleaner and beautifier

Do you have crappy HTML? I do!

<table width="100%" border="0" cellspacing="0" cellpadding="0">
        <tr>
          <td height="31"><b>Currently we have these articles available:</b>
 
        <blockquote>
              <p><a href="foo.html">The History of Foo</a><br />    
                An <span color="red">informative</span> piece  of <FONT FACE="ARIAL">information</FONT>.</p>
              <p><a href="bar.html">A Horse Walked Into a Bar</a><br/> The bartender said
                "Why the long face?"</p>
    </blockquote>
          </td>
        </tr>
      </table>

Just look at those blank lines and random line breaks, trailing spaces, mixed tabs, deprecated tags - it's outrageous!

Let's clean it up...

$ npm install clean-html

var cleaner = require('clean-html'),
    fs = require('fs'),
    file = process.argv[2];
 
fs.readFile(file, function (err, data) {
    process.stdout.write(cleaner.clean(data) + '\n');
});

Sanity restored!

<table>
  <tr>
    <td>
      <b>Currently we have these articles available:</b>
      <blockquote>
        <p>
          <a href="foo.html">The History of Foo</a><br>
          An <span>informative</span> piece of information.
        </p>
        <p>
          <a href="bar.html">A Horse Walked Into a Bar</a><br>
          The bartender said "Why the long face?"
        </p>
      </blockquote>
    </td>
  </tr>
</table>
