XML to PDF

I am really new to xml. How can i transform a xml file to a pdf ?

Would be grateful for any help with this.
Thanks!

That doesn't quite make sense, unless you just want to have the xml output appearing as XML text in the pdf document. XML by itself has no styles/display formatting in it, but a quick google search turned up XSL Formatting Objects which might do what you need.

I want to view the output of the xsl as a pdf document or even in HTML.
