Help needed - getting informations from XML File

AxLed

Hi to the java gurus,

i am having troubel to get to the right informations of an XML File.
I try to read a xml file of a TV set top box (Dreambox, Linux OS, Enigma2).
The xml file is provided by the webservice of the box in the same LAN (see sample below).
I already got following working reading the xml file into a variable (in node_helper.js) and sending this to the module.js.
I have to use JSON.stringify(xml) instead of JSON.parse(xml) otherwise i got an error of some special charachters found in xml.

Sample of XML

<?xml version="1.0" encoding="UTF-8"?>
<e2servicelistrecursive>
	<e2bouquet>
		<e2servicereference>1:7:1:0:0:0:0:0:0:0:FROM BOUQUET "userbouquet.favourites.tv" ORDER BY bouquet</e2servicereference>
		<e2servicename>Favourites (TV)</e2servicename>
		<e2servicelist>
			<e2service>
				<e2servicereference>1:0:19:2B5C:41B:1:FFFF014A:0:0:0:</e2servicereference>
				<e2servicename>Das Erste HD</e2servicename>
			</e2service>
			<e2service>
				<e2servicereference>1:0:19:2B66:437:1:FFFF01C2:0:0:0:</e2servicereference>
				<e2servicename>ZDF HD</e2servicename>
			</e2service>
		</e2servicelist>
	</e2bouquet>
</e2servicelistrecursive>

If i send the content of xml to console.log it shows me the right content, but the whole xml file.

Now i want to get only some datas out of the xml file, but the following didnt work:

this.reference = xml.e2servicereference;
this.e2servicelist = xml.e2servicelist;
this.reference = xml.e2servicereference[0];
this.e2servicelist = xml.e2servicelist[0];

I get an error that xml.whateveritrytoectract is undefined.

I tried to use code samples of MMM-RNV which unfortuantelly didnt work, but he is using JSON.parse(xml) instead of JSON.stringify(xml).

Does anybody has useful tipps for me?

I am looking forward to your answers.

Best regards

The easiest I have used is to conevrt to json
just add xml2json like I have used in my Bose Soundtouch module.

This is the link to the js file

with

var json=xml2json(data);

can use the variables quickly.

Good luck

@Charley
Thanks for your reply and your code in xml2json.js.
Now i can get the requested values of my xml and can move forward in developing.

If somebody knows a way to directly extract datas of xml could be an optimization afterwards, to reduce code.
