Angular2: Convert XML to JSON

Question

I wanted to convert the XML I received from Web API response to JSON in Angular 2. The application is developed in Nativescript. Not able to find a solution for this.

Answer 1

This is if you are doing a POST and getting back XML response using Angular 2: Use xml2js - https://www.npmjs.com/package/xml2js

1. npm install xml2js --save

2. import in service file as:

   import * as xml2js from 'xml2js';
   

3. Code:

   let formdata = new URLSearchParams();
   formdata.set('username','username');
   formdata.set('pw','pw'); 
   let headers = new Headers({'Content-Type': 'application/x-www-form-urlencoded' });
   
   let options = new RequestOptions({ headers: headers, method: RequestMethod.Post});
   
   postData () {
   
        this.http.post(this._yourUrl, formdata.toString(), options)
        //convert to JSON here
        .map(res => {
               xml2js.parseString( res.text(), function (err, result) {
               console.dir(result); // Prints JSON object!
            });
        })
        .subscribe(data => { 
             console.log(data);              
        });
   }
