Two ways to do XSLT processing on Linux

use xsltproc system command
use Python:

  from Ft.Xml import InputSource
    from Ft.Xml.Xslt.Processor import Processor

    document = InputSource.DefaultFactory.fromUri(xmlfile)
    stylesheet = InputSource.DefaultFactory.fromUri(xsltfile)
     # there's also a fromString() method
    
    processor = Processor()
    processor.appendStylesheet(stylesheet)
    result = processor.run(document)
