Hi,
sure enough I hit one of the 0.1% cases in the conversion :) Namely
the form feed char being present in the JSON which produced form feed
in the XML output which is not well-formed XML 1.0.
I've released JSON2XML version 1.0.5 which attempts to address this
issue by doing the default replacement of invalid characters to the
REPLACEMENT CHARACTER (xFFFD), as specified by the json-to-xml()
function.
Could you please take a look at the replacement code (copy-pasted from
StackOverflow :)) - does it look reasonable?

Nice.
You're not handling the edge cases such as duplicate keys, characters invalid
in XML, unpaired surrogates, etc, but I should think that's OK 99.9% of the
time.
Being able to write to a SAX ContentHandler might be more versatile than a
StAX XMLStreamWriter, since there are probably more things prepared to take
input from a SAX source without having to serialize the XML first.

Hi all,
I wanted to share a small utility I've created for our XML pipeline:
https://github.com/AtomGraph/JSON2XML
It is a streaming JSON to XML converter. It reads any JSON data and
produces XML Representation of JSON specified in XSLT 3.0 [1].
JSON2XML enables JSON transformation with XSLT even without having an
XSLT 3.0 processor. You can simply pre-process the data by having
JSON2XML before the transformation, and pipeline it into an XSLT 2.0
stylesheet, for example. That way your stylesheet stays forward
compatible with XSLT 3.0, as the XML representation is exactly the
same.
Admittedly I haven't done much testing, but I'm going to put into use
next month. The sample from the specification works :) The conversion
code is quite straightforward.
Also planning to create a Docker container out of it.
Feedback and pull requests are welcome.
