javascript解析xml

//1.创建DOM对象函数

varcreateXmlDom=function(){
   //通过对象/属性检测法，判断是IE来是Mozilla
  if (window.ActiveXObject)
  {
       var arrSignatures =["MSXML2.DOMDocument.5.0","MSXML2.DOMDocument.4.0",
                            "MSXML2.DOMDocument.3.0",
"MSXML2.DOMDocument","Microsoft.XmlDom"];                         
for (var i=0; i < arrSignatures.length; i++)
  {
     try 
     {        
       var oXmlDom = newActiveXObject(arrSignatures[i]);     
      }
      catch (oError)
     {

      }
  }
}else if (document.implementation&&document.implementation.createDocument)
  {     
    varoXmlDom=document.implementation.createDocument("","",null);
   }
    oXmlDom.async=false;
    return oXmlDom;

}

//2.Dom对象载入xml文件有两种方式，一种是文件载入，一个是xml字符串载入

//xml文件转换为对象数组
var xmlFileToArray=function(xmlfile)

{
 var oXmlDom = createXmlDom();
 //oXmlDom.async = false;
 try{
 oXmlDom.load(xmlfile);
 } catch(nerror){
  //ignore
 }
 returnxmlToObjectArray(oXmlDom.documentElement);
}

//xml字符串转换为对象数组
var xmlStringToArray=function(xmlstring)

{
 var oXmlDom = createXmlDom();
 //oXmlDom.async = false;
 try

{
 oXmlDom.loadXML(xmlstring);
 }

catch(nerror){

 }
 returnxmlToObjectArray(oXmlDom.documentElement);
 }

//3.将dom对象装载的xml转换为数组

varxmlToObjectArray=function(xmlRoot){
  var objArray = newArray;
 var tNode,pNode,i,j,n=0;
 vartmpString;    
 for(i=0;tNode=xmlRoot.childNodes[i];i++){
  if(tNode.nodeType ==3 )continue;
  tmpString = "var obj = newObject();";
  for(j=0;pNode=tNode.childNodes[j];j++){
   if(pNode.nodeType == 3 )continue;       
   tmpString+="obj." + getname(pNode) + "='" + getvalue(pNode) +"';";
    }
  eval_r(tmpString);
   objArray[n++]=obj;
  }
 return  objArray;

}

//4.获得节点名称和值

vargetname=function(pNode)

{returnpNode.attributes[0].nodeValue;}   
var getvalue=function(pNode)

{returnpNode.firstChild.nodeValue;}  

 

xml的格式：
