HTML Regex Replace use find&replace mechanism based on regexp 
for your posts/pages. Plugin finds html or text using regular 
expressions and replaces it with predefined ‘New string’. 
Unlimited replacement rules. You can specify any amount of short codes, and no buttons!
For example:
<pre><code>(c) -> Copyright
[me] -> My Full Name
</code></pre>
Short code ‘(c)’ will be replaced with ‘Copyright’ and ‘[me]’ with ‘My Full Name’.
More than that you can fix html code or remove unwanted automatically inserted html 
(for example, chrome-auto-translate-plugin-dialog inserted by Auto-Translate 
chrome plugin).
