XSLT stylesheet for transforming FHIR XML to JSON

FHIR XML => JSON via XSLT

This repository contains XSL 2.0 stylesheet fhir-xml2json.xsl for transformation of FHIR resources XML representation into JSON.

Such transformation requires metadata about FHIR resources structure, so main XSL stylesheet fhir-xml2json.xsl needs other file called fhir-elements.xml to be able to do conversion.

fhir-elements.xml is build from official FHIR metadata with XSL stylesheet called make-fhir-elements.xsl. Once fhir-elements.xml was built, you don't need make-fhir-elements.xsl to perform conversion.

Prerequisites

Basically you need some Unix environment (OSX or Linux are fine, Windows needs Cygwin). Specially, following components should be installed:

• Saxon XSLT processor
• make utility to build fhir-elements.xml automatically
• Python interpreter to pretty-print JSON when invoking make examples
• unzip binary to extract ZIP archives

Usage

Just clone this repo, cd into it and run make:

$ cd fhir-xml2json
$ make

If anything finished without errors, you will see fhir-elements.xml, which is XML file containing all metainformation required to perform XML => JSON conversion. In examples directory you'll find FHIR example resources converted to JSON.

Testing correctness of conversion

Invoke following commands:

$ make examples
$ make compare

Last command will output differences between JSON files converted with XSLT and original JSON examples.
