Are there any XSLT processing command line tools?

If you are looking for an XSLT processor you can use Saxon: http://saxon.sourceforge.net/

You can see the command line options here: http://saxon.sourceforge.net/saxon6.5.1/using-xsl.html

Microsoft has a simple command line tool that wraps their XML Parser - http://www.microsoft.com/en-us/download/details.aspx?id=21714.

As @Mathias said though, it only supports XSL 1.0 while Saxon supports XSL 2.0.

To run the convertor you downloaded from the given URL run this command

msxsl.exe backEnd.xml inspectcode.xslt -o backEnd.html

This will tranform the xml file using the xslt file into the output file in html format
