js字符串转换成xml并使用

print?//字符串转化为xml  
function toXmlDom(source){ 
    var xmlDoc = null; 
    if (window.ActiveXObject) { 
        var ARR_ACTIVEX =  
 
["MSXML4.DOMDocument","MSXML3.DOMDocument","MSXML2.DOMDocument","MSXML.DOMDocument","Microsoft.XmlDom"];

[Javascript]
//使用  
 
 function areaChart(data){ 
      var s = toXmlDom(xml);//xml为字符串  
   $(s).find("area").each( //得到每一个area标签  
     function(id,item){  
      var areaCode=$(item).find("area_code").eq(0).text();//获取area标签的内容  
      var num = $(item).find("area_all_num").eq(0).text(); 
      var name=$(item).find("area_name").eq(0).text(); 
      var title=name+","+num; 
     $("#"+areaCode+"").attr("title",title); 
      
    } 
  );
