Looking for free lightweight xslt editor

Question

As stated I'm looking for a free lightweight xslt editor with following functionalities:

• Intellisense support
• Simple to use (ie. can copy/paste xml & xsl into it and run the transformation)
• Can be used to preview resulting html
• Runs on Windows

Something like xmlspy used to be like (before it got pricey and full of features noone uses)

Answer 1

I have been using the XSelerator for more than 10 years. It is more than a good XSLT/XML editor.

Provides a good MSXML3/4 debugger and dynamic intellisense, import/include tree navigation, etc.
