json.transformToJson

json.transformToJson(
   node as Node,
   [config as Object]
) as Node?

Summary

This function transforms an XML document to JSON using the default ("basic") strategy if none is supplied.

Usage Notes

The supplied document (element or document node) is transformed to JSON using the default ("basic") strategy and returned as a document node containing a JSON node (object-node() or array-node()).

When the default "basic" strategy is used, the XML node must be in the http://marklogic.com/xdmp/json/basic namespace.

Note: Version of MarkLogic prior to 8.0.1 returned an xs:string. See https://docs.marklogic.com/guide/relnotes/chap4#id_92312

config.whitespace = 'ignore';
json.transformToJson( cts.doc('/sample.xml') , config );
