Linux command-line XSLT
To convert an XML based on a XSL, use this command:
$ xsltproc /path/to/xsl.xsl /path/to/xml.xml
The converted document will be written to STDOUT. To write to a particular file, you may use the -o parameter:
$ xsltproc /path/to/xsl.xsl /path/to/xml.xml -o out.html
Check the info/man pages for additional information.
