xml-to-json-promise

Convert an XML file or XML data to JSON (via xml2js), with promises.

This module is a promise-supported wrapper around the fabulous xml2js library. This module makes it easy to convert XML files, as well as raw XML data to the JSON format.

Install

npm install --save xml-to-json-promise

Usage

var convert = require('xml-to-json-promise');
 
// convert an xml file to json
convert.xmlFileToJSON('xmlfile.xml').then(json => {
    console.log(json);
});
 
// convert raw xml data to json
convert.xmlDataToJSON('<example>data</example>').then(json => {
    console.log(json);
});

var fs = require('fs');
 
convert.xmlDataToJSON('<example>data</example>').then(json => {
    fs.writeFile('file.json', JSON.stringify(json), err => {
        if (err) { throw err };
        console.log('file saved!');
    });
});
