XML : Convert json to xml and remove empty strings

I convert a json file to xml file and in my json file I have :

  “settingsData": {        “settingsname": “",      "username": “Dave",      "password": “",      "domain": “Benji”,  }    

My output is:

   <data name="settingsname" value=""/>   <data name="username" value="Dave"/>   <data name="password" value=""/>   <data name="domain" value="Benji"/>    

Here is my function :

  var settings = [];    function extractData(data, settingsData){          settings.push({          name : 'settingsname',          value : data. settingsname      });       settings.push({          name : 'username',          value : data. username      });      settings.push({          name : 'password',          value : data.password      });       settings.push({          name : 'domain',          value : data. domain      });   return settings;  }    

The outPut needs to be :

  <data name="username" value="Dave"/>  <data name="domain" value="Benji"/>    

My Question is how can I remove the empty strings or How can I check if it is an empty string then do not print it,

I used something like the following if statemnet, but it didn’t work :

   if(settingsData. settingsname !== "”){      settings.push({          name : 'settingsname',          value : data.settingsname      });      }    

Thanks in Advance!
