Hi, I read we can use prince to generate a pdf by using xml with this command line
prince.exe input.xml -o output.pdf

I would like to apply a XSL file.

I tried with -s input.xsl but I get this message: "warning: failed to parse all CSS rules"
I may have misunderstood something.

Prince does not support XSLT, but you can use an external XSLT processor like Saxon or xsltproc and then pass the resulting document to Prince.

I'll take a look to these processors
Thanks a lot !
