Another way for making soap request using strong-soap

const fs = require('fs');
const util = require('util');
const soap = require('strong-soap').soap;
const XMLHandler = soap.XMLHandler;
const xmlHandler = new XMLHandler();

const url = 'https://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl';
const options = {};

soap.createClient(url, options, async (err, client) => {
  let args = { LatLonListZipCode: 75001 };
  try {
    const { result, envelope } = await client.LatLonListZipCode(args);
    //response envelope
    console.log(`Response Envelope: \n${envelope}`);
    //'result' is the response body
    console.log(`Result: \n${JSON.stringify(result)}`);

    const node = xmlHandler.jsonToXml(
      null,
      null,
      XMLHandler.createSOAPEnvelopeDescriptor('soap'),
      result
    );
    const xml = node.end({ pretty: true });
    console.log(`xml:\n${xml}`);
    const root = xmlHandler.xmlToJson(null, xml, null);
    console.log(`root:\n${util.inspect(root, { depth: null })}`);
  } catch (err) {
    // handle error
    console.error(err);
  }
});

But the result also have to transform, the XMLHandler seems not enough.

The result of the following code is:
