js Convert Object to XML

本代码解决这两个问题：

1.已知js对象没有类名概念，所以转换时要手动指定顶级节点名称

2.还有数组内的元素如果是对象类型，需要配置此数组元素的节点名称

var XmlHelper = function() {
 var _arrayTypes = {};
 var _self = this;
 /*
 *转换对象为xml
 *@obj 目标对象
 *@rootname 节点名称
 *@arraytypes 配置数组字段子元素的节点名称
 */
 this.parseToXML = function(obj, rootname, arraytypes) {
 if(arraytypes){
  _arrayTypes=arraytypes;
 }
 var xml="";
 if(typeof obj!=="undefined"){
  if(Array.isArray(obj)){
  xml+}=parseArrayToXML(obj,rootname);
  }
  xml+=parseObjectToXML(obj,rootname);
  }
  xml+=parseGeneralTypeToXML(obj,rootname);
  }
 }
 return xml;
 }
 var parseObjectToXML=function(obj,rootname){
 if(typeof rootname==="undefined"||!isNaN(Number(rootname))){
  rootname="Object";
 }
 var xml="<"+rootname+">";
 if(obj){
  for(var field in obj){
  var value=obj[field];
  if(typeof value!=="undefined"){
   if(Array.isArray(value)){
   xml+=parseArrayToXML(value,field);
   }
   xml+=_self.parseToXML(value,field);
   }
   xml+=parseGeneralTypeToXML(value,field);
   }
  }
  }
 }
 xml+="</"+rootname+">";
 return xml;
 }
 var parseArrayToXML=function(array,rootname){
 if(typeof rootname==="undefined"||!isNaN(Number(rootname))){
  rootname="Array";
 }
 var xml="<"+rootname+">";
 if(array){
  var itemrootname=_arrayTypes[rootname];
  array.forEach(function(item){
  xml+=_self.parseToXML(item,itemrootname);
  });
 }
 xml+="</"+rootname+">";
 return xml;
 }
 var parseGeneralTypeToXML=function(value,rootname){
 if(typeof rootname==="undefined"||!isNaN(Number(rootname))){
  rootname=typeof value;
 }
 var xml="<"+rootname+">"+value+"</"+rootname+">";
 return xml;
 }
}
//===========Test=========
var xmlhelper=new XmlHelper();
//Example1
var testobj={
 field1:"1",
 field2:true,
 field3[{a:1},{a:2}]
 }
console.log(xmlhelper.parseToXML(testobj,"testobj",{field3:"ArrayItem"});
//Output:<testobj><field1>1</field1><field2>true</field2><field3><ArrayItem><a>1</a></ArrayItem><ArrayItem><a>2</a></ArrayItem></field3></testobj>
console.log("================================================");
//Example2
var testobj2=[1,2,3]);
console.log(xmlhelper.parseToXML(testobj2,"testobj2"));
//Output:<testobj2><number>1</number><number>2</number><number>3</number></testobj2>

This conversion code has usage restrictions

It is better not to have the same field name for the field that is an array in the object
