I want to transform an xml file, display its treeview on a html. I have downloaded a example, it has xslt, js, css and also some images. I used xmlspy to do the transformation, but it didn't work.
Could anyone please tell me how to do the transformation?
W3Schools has a good explanation on how to Transform XML using XSL.
[EDIT] After re-reading your question, it seems that you are looking for a tool to apply XSL to your XML file and which outputs the result? Have you already tried XML Notepad 2007?
I'm guessing this is the example you're using. In which case, you shouldn't have to use XMLSpy to do the transformation. A newer browser will have an XSLT processor built-in! Try using the latest version Firefox or IE!
If you find it easier (as I do) to do as much in the browser as poss take a look at Johann Burkard's xslt.js:

You can do/test your transformation right in the browser :)
