However, the xml-to-json function on XSLT 3.0 doesn't convert arbitrary XML to
JSON; it requires you first to do a transformation to the XML structure that
reflects the JSON you want to produce.
Generally, off-the-shelf tools that convert arbitrary XML to JSON tend to
produce JSON that's not very nice to work with.

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,

There are also non XSLT converters that use SAX: read XML and serialize out
as JSON.
There are several node-js packages.
Python xmljson. https://pypi.org/project/xmljson/
<https://pypi.org/project/xmljson/> supports several different JSON encoding
conventions.
And I’m sure many others.
( I’ve used the Python package, but not for any large projects. )

Hi Folks,
We're looking to do conversion of relatively complex XML (i.e.
namespaces, attributes, repeating elements, xlinks) into JSON from
the
Unix command line to build a web page. We've used the XML to JSON
feature in the Oxygen Developer tool, and it works well, but that's
a
GUI, not a command line tool.
It's probably using XSLT under the hood, with a stylesheet that's
usable e.g. with Saxon. You do pay the penalty of Java runtime startup,
though.
Note also that XSLT 3 includes a standard function to produce JSON; see
https://www.w3.org/TR/xpath-functions-31/#json-to-xml-mapping
<https://www.w3.org/TR/xpath-functions-31/#json-to-xml-mapping>
So you could just use xml-to-json() in XSLT. You may need Saxon EE for
that, i'm not sure offhand.
Of course, you could also just send XML to the Web client; what you are
doing by using a complex transformation into JSON is moving the
complexity from one developer to another. You could also generate HTML
on the server, whic might make it easier to meet 508/WCAG requirements
:)
