Regex to remove extra attributes

I need a regex that can strip out the extra mce_src or mce_href attributes from a string.
FYI: The location of the "mce_*" attributes could be on either side of the src or href attributes.


If this helps, I think this is how Wordpress does it in javascript:
I could be mistaken though.
s= s.replace(new RegExp('mce_src\\s*=\\s*\"[^ >\"]*\"', 'gi'), '');
s= s.replace(new RegExp('mce_href\\s*=\\s*\"[^ >\"]*\"', 'gi'), '');
s= s.replace(new RegExp('mce_src\\s*=\\s*\"[^ >\"]*\"', 'gi'), '');
s= s.replace(new RegExp('mce_href\\s*=\\s*\"[^ >\"]*\"', 'gi'), '');


Below is what it looks like.

This "img" tag:

<img mce_src="http://www.google.com/intl/en_ALL/images/logo.gif" src="http://www.google.com/intl/en_ALL/images/logo.gif" height="110" width="276">

should look like this:

<img src="http://www.google.com/intl/en_ALL/images/logo.gif" height="110" width="276">




This "a" tag:

<a href="http://www.domain.com/mypage.php" mce_href="http://www.domain.com/mypage.php">My link</a>

should look like this:

<a href="http://www.domain.com/mypage.php">My link</a>
