Parse XML in angular2

Question

The question is how to convert xml to json format in angular2? I currently receive the xml from an external page

My service:

import { Injectable } from '@angular/core';
import {Http } from '@angular/http';

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/throw';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

@Injectable()
export class Ganado2Service {

    private url: string = 'http://bicicardpruebas.itcl.es/prodwservice/api/instalacion'

    constructor(private http: Http) { }

    getCiudad(id: number) {
        return this.http.get(this.url + '/' + id)
            .map(response =>  response.text())  
            .catch(this.handleError)
            .subscribe(data => {
                if(data) {
                    console.log(data); 
                }
            })

    }

    handleError(error: any) {
        let errMsg = (error.message) ? error.message :
        error.status ? `${error.status} - ${error.statusText}` : 'Server error';
        console.error(errMsg);
        return Observable.throw(errMsg);
    }
}

My component:

export class GanadoComponent implements OnInit {

    constructor(private ganadoService: Ganado2Service) { }

    ngOnInit() {
        this.ganadoService.getCiudad(1).subscribe();
    }

}

I do not know what to write inside subscribe.

I want it to return all the xml data.

XML:

<CL_Instalacion xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ClasesComunes">

  <AcquirerBin i:nil="true"/>
  <AvisosAltasPimEmailsDestino>[email protected]
  </AvisosAltasPimEmailsDestino>
  <AvisosAltasWebEmailsDestino i:nil="true"/>
  <AvisosEmailOrigen>[email protected]</AvisosEmailOrigen>
  <AvisosEmailOrigenEnabledSSL>true</AvisosEmailOrigenEnabledSSL>
  <AvisosEmailOrigenHost>smtp.gmail.com</AvisosEmailOrigenHost>
  <AvisosEmailOrigenPassword>contrasenafrioindustrial
  </AvisosEmailOrigenPassword>
  <AvisosEmailOrigenPuerto>587</AvisosEmailOrigenPuerto>
  <AvisosIncidenciasEmailsDestino>[email protected],[email protected]
  </AvisosIncidenciasEmailsDestino>
  <AvisosOcupacionEmailsDestino>[email protected]
  </AvisosOcupacionEmailsDestino>
  <Ciudad>Burgos</Ciudad>
  <ClaveEncriptacion i:nil="true"/>
  <HabilitadoHorario>true</HabilitadoHorario>
  <Hora>2017-10-27T12:55:51.1868855+02:00</Hora>
  <IdiomasPorDefecto>FR</IdiomasPorDefecto>
  <MaxBicis>5</MaxBicis>
  <id>1</id>

</CL_Instalacion>

How can I do to parse it to json? so I can get the fields I need.

Thanks

You could parse XML via DOMParser:

https://www.w3schools.com/xml/xml_parser.asp

Example usage:

var text, parser, xmlDoc;

text = "<bookstore><book>" +
    "<title>Everyday Italian</title>" +
    "<author>Giada De Laurentiis</author>" +
    "<year>2005</year>" +
    "</book></bookstore>";

parser = new DOMParser();
xmlDoc = parser.parseFromString(text,"text/xml");

document.getElementById("demo").innerHTML = xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue;

Then you would probably need to map that to JS object manually.

Or use some ready made solution, like this:
