You may have some obscure reason for wanting the output that is sent by the_content() and get_the_content() to be simple HTML, free of the more exotic tags and objects. It may be for post aggregators or email notifications or some other edge case. This is for you!

Remove HTML From Content

Simple plugin that strips all but the most common HTML tags from the content of WordPress pages and posts.

CommentSafe is a really simple plugin that I’ve written for WordPress. Very simply, it takes a list 
of (X)HTML tags – which you can specify through the admin interface – and does one of three things 
with those tags, when they’re found in your comments:
<ol>
<li>Strip tags (example: <code>A bold choice</code> becomes <code>A bold choice</code> – default)</li>
<li>Convert tags (example: <code>A bold</code> choice becomes <code>A &lt;b&gt;bold&lt;/b&gt; choice</code>)</li>
<li>Remove tags and content (example: <code>A bold choice</code> becomes <code>A choice</code>)</li>
</ol>
The comments are changed before being saved to your WordPress database so that, if you decide to 
uninstall or deactivate CommentSafe, your comments will remain sanitised and safe.
