Plugin for clean up HTML code in your Wordpress posts by one click

This Wordpress plugin has similar functionality as PASTE without formatting,
but preserve semantic tags like <strong>, <pre> etc.

omCleaner is smart and only remove unwanted wrappers (<div>, <span>) and
attributes (id="", class="", style="") from your HTML code :-)

PS: it's one button in wysiwyg editor check the screenshot

And it's opensource https://github.com/OzzyCzech/omCleaner
