Usage

XSLT

In XSLT, it is recommended that you specify the intended media type in the output properties of your XSLT with the <xsl:output> element as:

<xsl:output method="xml" media-type="application/json"/>

This explicitly says that the stylesheet produces XML but intends to generate JSON data.

Java

In Java, you can directly specify the Result implementation to use as JSON result.

TransformerFactory factory = TransformerFactory.newInstance();
Source xslt = new StreamSource(new File("stylesheet.xsl"));
Transformer transformer = factory.newTransformer(xslt);
Source source = new StreamSource(new File("source.xml"));
JSONResult result = new JSONResult(System.out);
transformer.transform(source, result);

Or if you already have StreamResult, you can simply build a new one after checking the output properties of the Transformer:

StreamResult result = new StreamResult(new File("result.json"));
// Check that XSLT specifies method "xml" and media type "application/json"
if (JSONResult.supports(transformer))  {
  Result jsonresult = JSONResult.newInstance(result);
  transformer.transform(source, jsonresult);
} else {
  transformer.transform(source, result);
}

Berlioz

From version 0.9.21, Berlioz has built-in support for Aeson, simply include the JSON processing API and set the output properties of your XSLT as described above and Berlioz should automatically produce JSON.
