All Implemented Interfaces:

PullEvent, Callable, Function, GroundedValue, Item, Sequence

public class XMLToJsonTransform
extends SystemFunction

Implement the XML to JSON conversion as a built-in function - fn:xml-to-json()

This exploits the stylesheets xml-to-json.xsl and xml-to-json-indent.xsl, to perform the actual conversion. These are held as resources within the Saxon jar and compiled when needed.
