This expression has type 'void' and can't be used

Question

I am trying to parse XML to JSON and for that I have used Xml2JSON package. When I am using this it is resulting me an error:

Error: This expression has type 'void' and can't be used.

Here is my code:

Xml2Json xml2json = new Xml2Json();
String json = xml2json.parse(data);

Solution

Checking the example in the docs for the plugin you're using, I believe that .parse methods returns void.

As the example shows, you should first parse and then transform to json with one of the different methods (.toBadgerfish, .toGData(), toParker()).

Hence, your code should be something like this:

Xml2Json xml2json = new Xml2Json();
xml2json.parse(data);
String json = xml2json.toBadgerfish();
