Does anyone have a good, production proven XSLT for cleaning up pasted content in Rich Text Fields (Tridion 2013 SP1). I had a hunt around, could only find this one from Bart which may be good enough, but I wondered if anyone had any other good ones. I am particularly interested in ensuring that content copy-pasted from web pages and MS word documents is cleaned down to semantic/structural markup only.

Are you looking for XSLT only or GUI extension(with its own textbox) work for you?– Raj KumarJun 17, 2014 at 8:35

Not sure what you mean by GUI extension, but I was thinking of just a cleanup XSLT– Will PriceJun 17, 2014 at 8:38

i mean we are using GUI extension for cleanup purpose before copying it into the RTF. so it cleanup content pasted from word or html doc.– Raj KumarJun 17, 2014 at 8:43

Here is one I used a while ago (quite similair to the one before, but with a little extra ;o), it removes the font element and attributes like align, valign, border, cellpadding, cellspacing. It also removes all style attributes, unless they contain text-align, since that is what the default table editor uses to center align text in a cell.
The last bit of cleanup is removing rowspan and colspan attributes if their value is 1 (which is pointless ;o) and I remove some well know Microsoft Word classes like MsoNormal and MsoTableGrid
