@sdetweil Yeah! That part is working. Now I’ve an other error which has something to do with the xmlToJson function:

Whoops! There was an uncaught exception...
TypeError: xml.hasChildNodes is not a function

Any idea?

[sdetweil]

@htilburgs yeh, tricky crap… they had a special runtime that supported that… sorry…
have to use one of the libs…

in your module folder do

npm install xml2js

then in your code

const xml2js = require('xml2js');

then

getMTVM: function(url) {
               let self=this
		request(url, function(err, res, body) {
		        // if no error and server was happy
			if(err == null && res.statusCode ==200){
			   console.log(body);
			   xml2js.parseString(body,function (err,result) {
			       let json_data = result // not needed but may make more clear
			       console.log("Text is " + json_data.film[0].titel)			   
			   });		   
			}
		});
	},

@sdetweil Almost there I think ;-)

Whoops! There was an uncaught exception...

Has this something to do with the json_data.film[0].titel ??
Or is it something else?

When I remove .film[0].titel I got:

Text is [object Object]
200[object Object]

@htilburgs u should look at the data format

getMTVM: function(url) {
               let self=this
		request(url, function(err, res, body) {
		        // if no error and server was happy
			if(err == null && res.statusCode ==200){
			   console.log(body);
			   xml2js.parseString(body,function (err,result) {
			       let json_data = result // not needed but may make more clear
			       console.log(JSON.stringify(json_data))			   
			   });		   
			}
		});
	},

@sdetweil JSON is perfect:

Thanks for the help so far!! Now I have my data I can play around with it.
