I downloaded Poweredit the other day from Alex Deyer. I liked it a lot, but I am trying to create an XHTML Strict site and this wouldn't do it for me. So I hacked his hack and the excellent functions he built are now XHTML compliant.
Here's a link to the files of his Poweredit, with XHTML instead: http://www.pidlubny.com/downloads/poweredit-xhtml.zip
I've tested it and it seems to work in all cases for me.
Enjoy,
