I need to download a free XSLT Editor

I am fairly new to XLST and trying to find a free XSLT editor to download. So far I have found EditX and Cooktop, however I am not sure which one would be better for me seen I am a novice. I need one that is easy to use and understand, not complicated, user friendly, intuitive, etc. In other words an editor for a “dummy”. Can anyone recommend a free XSLT editor of this nature?
