Often, when writing an XSLT file, you’ll want to test it quickly, without contacting a FileMaker Server or otherwise accessing the rest of the world. On Linux and OS X, you can use the command-line utility, ‘xsltproc’, to run XSLT programs quickly:
xsltproc transform.xsl input.xml
This applies the stylesheet in the file transform.xml to the XML in input.xml, and writes the output to your terminal. You can instead write the output to a file:
xsltproc transform.xsl input.xml > output.xml
