Details

var JsonPath = require('jsonpath-plus');

At its simplest the result is expressed as

var result = JSONPath({json: obj, path: path});Where obj is the name of the JSON object to evaluate and path is the JSONPath expression. See the www.npmjs.com/package/jsonpath-plus (opens new window) documentation for detailed examples of path expressions.

Example

An extended example of JsonPath is included in the GOSS.Examples.NodeModules group of the End Point library.

function(params, credentials) {
    var JsonPath = require('jsonpath-plus'),
        result = null,
        json = {
