XML to JSON for RSS

Ionic Framework ionic-v3

Hello there,

I am trying to use XML API for making RSS, I need to convert XML to JSON, but I have some problems, could you help me to solve them.

home.ts

import { NavController } from 'ionic-angular';
import { Component } from '@angular/core';
import { RssService } from '../../providers/rss-servise';
import { DetailPage } from '../detail-page/detail-page';


@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
    providers: [RssService]
})
export class HomePage {

  public entries: any  = []; /* this needs to be class level variable */

  constructor(public rssService:RssService, public nav:NavController) {    
  }

  ionViewDidLoad(){
      this.rssService.load().subscribe(
          data => {
              this.entries.push(data); /* push retrieved data into the array */
              
          }
      );
  } 

  openPage(entry) {
      console.log('open page called with '+ entry.title);
      this.nav.push(DetailPage, {selectedEntry:entry});
  }

}

rss-servise.ts

import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/add/operator/map';
import {Observable} from 'rxjs/Observable';
import * as xml2js from "xml2js"


@Injectable()
export class RssService {

  constructor(public http: Http) {
    console.log('Hello RssService Provider');
  }

  load() {

    

 return Observable.create(s => {
        this.http.get('https://lenta.ru/rss/top7').map(res => {
let data = res.json();
xml2js.parseString(data, ((result) => {
console.log(result);
return result;
  }));
}) 
 .subscribe(result => {
            console.log(result);
           var items = data.query.results.item;
           items.forEach(i=>s.next(i));
           s.complete();
        });
      });
 }

}

detail-page.ts

import {NavController, NavParams} from 'ionic-angular';
import { Component } from '@angular/core';



@Component({
    selector: 'detail-page',
    templateUrl: 'detail-page.html',

})
export class DetailPage {
      entry:any = {};
    constructor(public nav: NavController, navParams:NavParams) {
        console.log('run');
        this.nav = nav;
        this.entry = navParams.get('selectedEntry');
        console.log('my entry is '+ this.entry.title);
    }
}

Thank you in advance.
