Re: XSLT code for XML to JSON conversion?

Hi,

Saxon on the Java Platform would work fine on the command-line, but as Liam
said you have the Java runtime startup.

Alternatively Saxon/C could equally fit your requirements. It is cross
compiled to native library, which can be run on the command-line using C/C++.
Saxon/C also comes with Python extension API.

kind regards,

O'Neil

<https://pypi.org/project/xmljson/> supports several different JSON encoding
