javascript - convert flat json object into hierarchical xml -

i have json object this:

    var client = {   "id": 1,   "name": "john doe",   "name2": "jane doe",   "email": "john@test.com",   "phone": "+1-306-5555555",   "phonetype": "home",   "phone2": "+1-306-5556666",   "phone2type": "business",   "gender": "male",   "address": "1000 center ave",   "postcode": "s7j 1p3",   "city": "saskatoon",   "province": "sk",   "country": "ca",   "dob": "1990-12-11t02:00:00.000z",   "maritalstatus": "single",   "occupation": "software developer",   "createdat": "2015-12-07t08:14:21.000z",   "updatedat": "2016-01-19t13:35:10.000z" }; 

which want convert xml, isn't problem know there great library x2js can me.

my problem xml file, need follow standard this:

   <generalpartyinfo> <nameinfo>     <personname>         <surname>doe </surname>         <givenname>john</givenname>     </personname>     <supplementarynameinfo>         <supplementaryname>jane doe</supplementaryname>     </supplementarynameinfo> </nameinfo> <addr>     <detailaddr>         <streetname>centre</streetname>         <streetnumber>1000</streetnumber>         <csio:streettypecd>ave</csio:streettypecd>     </detailaddr>     <city>saskatoon</city>     <stateprovcd>sk</stateprovcd>     <postalcode>s7j 1p3</postalcode>     <countrycd>ca</countrycd> </addr> <communications>     <phoneinfo>         <phonetypecd>phone</phonetypecd>         <communicationusecd>home</communicationusecd>         <phonenumber>+1-306-5555555</phonenumber>     </phoneinfo>     <phoneinfo>         <phonetypecd>phone</phonetypecd>         <communicationusecd>business</communicationusecd>         <phonenumber>+1-306-5556666</phonenumber>     </phoneinfo> </communications> 

you can xml nested while json isn't, not mention name need spliced firstname , lastname , inside personname child of nameinfo, , generalpartyinfo root parent (same thing address).

there 2 problems have, first 1 missing tags example firstname inside personname inside nameinfo inside generalpartyinfo , can't this

  var firstname = client.name.split(' ').slice(0, -1).join(' ');   var lastname =  client.name.split(' ').slice(-1).join(' ');   delete client.name;  client.personname.push({         givename: firstname,         surname: lastname, }); 

because json object not array, requires me convert json array (which not recommended other professionals here in so), or can save each 1 (name, address, communication) separate json object concat of them abdthe way found in add parent json object this

  var obj = {fistname: client.name.split(' ').slice(0, -1).join(' '), lastname: client.name.split(' ').slice(-1).join(' ');};      var obj2 = { "personname" : obj };      var obj3 = { "nameinfo" : obj2 }; 

my second problem find way replace keys example want replace postcode postalcode or phonetype communicationusecd

or way

    var xml =  "<generalpartyinfo><nameinfo><personname>    <surname>" + client.name.split(' ').slice(0, -1).join(' '); + "</surname>    <givenname>"+client.name.split(' ').slice(-1).join(' ')+"</givenname>" 

but solution tedious, not efficient , doesn't pretty , i'm looking more stability , cleanliness of code.

for example how can manipulate json object add parent selected elements can replace keys through list have keys replaced example.

 var translationobj = {       "firstname": "givenname",       "lastname": "personname",      } 

ps: have lodash/underscore installed solution using underscore great.
